It gets rinsed out again after 1 to 3 minutes, and the cause sits at the dermal papilla of the hair follicle, according to the NIH database StatPearls up to about 4 millimetres below the skin surface. What a shampoo can genuinely do is treat the scalp, and that is worth more than it first sounds.<\/p>\n<p style=\"margin:0 0 8px;color:#013366;font-weight:700;font-size:16px\">The key points at a glance<\/p>\n<ul style=\"margin:0 0 14px;padding:0;color:#2e3033;list-style:none\">\n<li style=\"position:relative;padding:3px 0 3px 24px\"><span style=\"position:absolute;left:0;top:3px;color:#0079F1;font-weight:700\">&#10003;<\/span>No shampoo stops androgenetic hair loss: the contact time is too short and the cause sits too deep<\/li>\n<li style=\"position:relative;padding:3px 0 3px 24px\"><span style=\"position:absolute;left:0;top:3px;color:#0079F1;font-weight:700\">&#10003;<\/span>Ketoconazole 2% is the only shampoo ingredient with clinical data on hair density, but in the UK it is licensed for dandruff and seborrhoeic dermatitis, not for hair loss<\/li>\n<li style=\"position:relative;padding:3px 0 3px 24px\"><span style=\"position:absolute;left:0;top:3px;color:#0079F1;font-weight:700\">&#10003;<\/span>Caffeine shampoo is popular, yet the evidence comes almost entirely from hair follicles cultured in the lab<\/li>\n<li style=\"position:relative;padding:3px 0 3px 24px\"><span style=\"position:absolute;left:0;top:3px;color:#0079F1;font-weight:700\">&#10003;<\/span>Against dandruff, itching and seborrhoeic dermatitis, on the other hand, an active-ingredient shampoo is the proven standard treatment<\/li>\n<\/ul>\n<p style=\"margin:0 0 12px;color:#2e3033\">The table of contents shows what you will find where.

Both require dwell time and concentration. A cleansing product that is lathered up and rinsed off again delivers neither in any relevant amount.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The real bottleneck is therefore not the active ingredient but the dosage form: rinse-off versus leave-in. A <a href=\"\/uk\/blog\/minoxidil-hair-loss\/\">minoxidil<\/a> solution stays on the scalp for hours and, according to the patient information issued by the Royal Berkshire NHS Foundation Trust (October 2025), is used continuously, usually twice a day. A shampoo disappears down the plughole.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That also explains why no shampoo shows up in the treatment recommendations. The European S3 guideline on the treatment of androgenetic alopecia (Kanti et al., JEADV 2018) and the NHS, in its patient information on hair loss, name topical minoxidil and prescription medicines as the options with solid data behind them, not a wash-off product.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is one exception, and it is the reason for the rest of this article: ingredients that work on the skin surface and at the follicular opening do not need to reach any depth at all. Antifungals against the yeast Malassezia are among them. For those, a shampoo is in fact the right dosage form.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\" style=\"max-width:560px;margin-left:auto;margin-right:auto\"><img loading=\"lazy\" decoding=\"async\" width=\"1536\" height=\"1024\" src=\"https:\/\/elithair.com\/uk\/wp-content\/uploads\/sites\/3\/2026\/08\/kontaktzeit_diagramm__uk.png\" alt=\"Diagram: cross-section of the scalp showing a hair follicle up to 4 mm deep, next to a comparison of a shampoo's short contact time of 1 to 3 minutes with rinse-off and leave-in products\" class=\"wp-image-96278\" style=\"width:560px;max-width:100%;height:auto\" srcset=\"https:\/\/elithair.com\/uk\/wp-content\/uploads\/sites\/3\/2026\/08\/kontaktzeit_diagramm__uk.png 1536w, https:\/\/elithair.com\/uk\/wp-content\/uploads\/sites\/3\/2026\/08\/kontaktzeit_diagramm__uk-300x200.png 300w, https:\/\/elithair.com\/uk\/wp-content\/uploads\/sites\/3\/2026\/08\/kontaktzeit_diagramm__uk-1024x683.png 1024w, https:\/\/elithair.com\/uk\/wp-content\/uploads\/sites\/3\/2026\/08\/kontaktzeit_diagramm__uk-768x512.png 768w\" sizes=\"(max-width: 767px) 100vw, 660px\" \/><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\">What an anti-hair-loss shampoo can actually deliver<\/h2>\n\n\n\n<div style=\"border:1px solid #cfe0f7;border-left:4px solid #0079F1;background:#f6f9fc;border-radius:8px;padding:14px 16px 15px;margin:0 0 24px\">\n<div style=\"margin:0 0 7px\"><span style=\"display:inline-block;background:#013366;color:#ffffff;font-size:11px;font-weight:700;letter-spacing:.06em;text-transform:uppercase;padding:4px 9px;border-radius:4px;vertical-align:middle\">Short answer<\/span> <span style=\"color:#013366;font-weight:700;font-size:19px;vertical-align:middle\">In part.<\/span><\/div>\n<p style=\"margin:0;color:#2e3033;font-size:16px;line-height:1.6\">An anti-hair-loss shampoo treats the scalp, not the genetics of the follicle: five effects are realistic, and the best documented one is the treatment of dandruff and seborrhoeic dermatitis.<\/p>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>1. Scalp environment and barrier.<\/strong> Sebum, sweat, styling residue and dead skin flakes collect at the follicular opening. A shampoo removes them reliably. A calm, intact scalp is the basis for everything else, but it will not bring an already miniaturised follicle back.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2. Treating dandruff and seborrhoeic dermatitis.<\/strong> This is where the best-documented benefit lies. A pooled global prevalence estimate comes to around 4.4% of the population, while older individual figures range between 1 and 10% depending on the method used, with a peak between the ages of 30 and 60. Topical antifungals are the first-line treatment when the scalp is involved.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\" style=\"max-width:720px;margin-left:auto;margin-right:auto\"><img loading=\"lazy\" decoding=\"async\" width=\"1536\" height=\"1024\" src=\"https:\/\/elithair.com\/uk\/wp-content\/uploads\/sites\/3\/2026\/08\/kopfhaut_schuppen.png\" alt=\"Macro shot of a parting with slightly reddened scalp and fine white flaking\" class=\"wp-image-96279\" style=\"width:720px;max-width:100%;height:auto\" srcset=\"https:\/\/elithair.com\/uk\/wp-content\/uploads\/sites\/3\/2026\/08\/kopfhaut_schuppen.png 1536w, https:\/\/elithair.com\/uk\/wp-content\/uploads\/sites\/3\/2026\/08\/kopfhaut_schuppen-300x200.png 300w, https:\/\/elithair.com\/uk\/wp-content\/uploads\/sites\/3\/2026\/08\/kopfhaut_schuppen-1024x683.png 1024w, https:\/\/elithair.com\/uk\/wp-content\/uploads\/sites\/3\/2026\/08\/kopfhaut_schuppen-768x512.png 768w\" sizes=\"(max-width: 767px) 100vw, 660px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\"><strong>3. Reducing inflammation and itching.<\/strong> Anyone who scratches less does less damage to the hair shaft and the scalp, and perifollicular micro-inflammation is discussed as a contributing factor in thinning. If redness, weeping or pustules persist, though, the scalp needs to be seen by a doctor. More on this in our articles on <a href=\"\/uk\/blog\/scalp-infection\/\">scalp inflammation<\/a> and <a href=\"\/uk\/blog\/hair-root-infection\/\">folliculitis<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>4. Acting as a carrier.<\/strong> For substances meant to work on the surface, a shampoo is a good vehicle. For anything that has to reach deep into the dermis, it is a poor one. That single distinction explains almost every disappointment with a hair loss shampoo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>5. Reducing hair breakage.<\/strong> Conditioning formulas make the hair shaft smoother and more resilient. If fewer hairs break, you end up with visibly more hair, without a single follicle having been saved. A real effect, but a purely cosmetic one, and advertising likes to sell it as growth.<\/p>\n\n\n\n<style>\n@media (max-width:640px){\n.rt-table-wrap{overflow-x:visible!important;border:0!important;border-radius:0!important}\n.rt-table{min-width:0!important}\n.rt-table thead{display:none}\n.rt-table,.rt-table tbody,.rt-table tr,.rt-table td{display:block;width:100%}\n.rt-table caption{display:block;padding:0 0 12px!important}\n.rt-table tr{margin:0 0 12px;border:1px solid #dbe4f0;border-radius:10px;overflow:hidden}\n.rt-table tr:last-child{margin-bottom:0}\n.rt-table td{display:flex!important;flex-direction:column;gap:3px;padding:12px 14px!important;\nborder:0!important;border-bottom:1px solid #e3e8ef!important;background:#ffffff!important}\n.rt-table tr td:last-child{border-bottom:0!important}\n.rt-table td::before{content:attr(data-label);font-size:12px;font-weight:700;letter-spacing:.04em;\ntext-transform:uppercase;color:#5799F1}\n.rt-table td:not([data-label])::before,.rt-table td[data-label=\"\"]::before{display:none}\n}\n<\/style>\n<div class=\"rt-table-wrap\" style=\"overflow-x:auto;-webkit-overflow-scrolling:touch;margin:28px 0;border:1px solid #dbe4f0;border-radius:12px\">\n  <table class=\"rt-table\" style=\"width:100%;min-width:660px;table-layout:fixed;border-collapse:separate;border-spacing:0;font-size:15px;margin:0\">\n    <caption style=\"caption-side:top;text-align:left;color:#003366;font-weight:700;font-size:16px;line-height:1.35;padding:14px 16px 10px;background:#ffffff\">Scalp symptom matrix: what your scalp is telling you and what a shampoo can do about it.

class=\"wp-block-paragraph\">Ketoconazole (INCI: <em>Ketoconazole<\/em>) is the only shampoo ingredient with clinical data on hair density in androgenetic alopecia. In 1998, Pi\u00e9rard-Franchimont et al. reported in the journal <em>Dermatology<\/em>  an increase in hair density, hair shaft diameter and anagen ratio in 39 men with hair loss at the vertex who used a 2% ketoconazole shampoo over 21 months, comparable to a 2% minoxidil group.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That study is a signal, not proof: a small sample, a partly uncontrolled design, and no confirmation in a large randomised trial since. Anyone selling it as evidence for a hair growth shampoo is stretching it considerably.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The regulatory picture is unambiguous. In the UK, ketoconazole 2% shampoo is a licensed medicine for dandruff and seborrhoeic dermatitis of the scalp, classified as a pharmacy medicine (P): you can buy it without a prescription, but only over the counter at a pharmacy. Hereditary hair loss is not a licensed indication. Using it against hair loss is off-label, an approach that is being studied scientifically and belongs in a doctor&#8217;s hands.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practical terms: 1 gram of shampoo contains 20 milligrams of ketoconazole, which is 2%. The licensed regimen is twice a week over 2 to 4 weeks, then once a week to prevent recurrence. Because it is a pharmacy medicine, you can ask for it at the counter without a prescription, but you will not find it on the supermarket shelf. The details are in our article on how effective ketoconazole is against hair loss.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Piroctone olamine: the current anti-dandruff standard<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Piroctone olamine (INCI: <em>Piroctone Olamine<\/em>) is the anti-dandruff standard wherever zinc pyrithione has disappeared from the shelf, which is the case throughout the EU. Great Britain retained the European cosmetics rules only as they stood at the end of 2020 and has run its own ever since, while the EU ban followed in 2022. The European ceiling, based on the underlying SCCNFP assessment, is 1.0% in rinse-off products and 0.5% in leave-on products. Shampoos usually declare 0.1 to 1%.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Its effect against Malassezia and flaking is well documented, and there is no data on hair density in androgenetic alopecia. Put honestly, the substance helps your scalp, not your hair growth. For many people buying an anti-hair-loss shampoo, that is nevertheless exactly the effect they were really looking for.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Salicylic acid: loosens flakes, grows no hair<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Salicylic acid (INCI: <em>Salicylic Acid<\/em>) is a keratolytic and is typically used in cosmetics at 0.5 to 3%. It loosens stubborn layers of flaking and hardened keratin at the follicular opening, which is what allows other ingredients to reach the skin in the first place.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is not a hair growth product, it is a preparatory step. The flip side matters for safety: salicylic acid also increases the absorption of other topicals you apply. So if a dermatologist has prescribed you a solution or a foam, discuss the combination first.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Selenium sulfide: strong against fungus, hard on the hair<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Selenium sulfide (INCI: <em>Selenium Sulfide<\/em>) is strongly antifungal and is used against dandruff and seborrhoea. In Europe it is permitted in anti-dandruff shampoos at up to 1%, and Great Britain has set its own cosmetics rules since leaving the EU. It has no effect on hair density in hereditary hair loss.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Two practical downsides are listed on the product labelling: selenium sulfide dries out hair and scalp and can discolour colour-treated or bleached hair. How to cushion that without giving up the treatment is covered further down in the application section.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Aminexil and peptides: tested as a leave-in, sold as a shampoo<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Aminexil and peptide complexes such as Capixyl, Redensyl or Procapil are in-house developments by the manufacturers. The available studies are small, largely industry-linked and, this is the decisive point, mostly carried out with leave-in formulations: with tinctures, serums or ampoules that stay on the scalp.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An ingredient that was studied in a tincture is not automatically effective in a shampoo that gets rinsed out. So if you want to check an advertising claim, look for the dosage form in the study reference. If it says lotion or serum, it says very little about the shampoo in your hand.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Plant extracts and biotin in shampoo<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Rosemary oil, nettle, saw palmetto, pumpkin seed and biotin are the classics among plant-based additives. The most frequently cited work is by Panahi et al. (2015), which compared rosemary oil with minoxidil 2%. It is methodologically limited, and it studied an oil that stayed on the scalp, not a shampoo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Biotin applied from the outside cannot supply the hair shaft with nutrients, because the visible part of the hair consists of dead keratin. Biotin works, if at all, systemically and only in a documented deficiency. In a shampoo it is a conditioning ingredient, not a growth factor.<\/p>\n\n\n\n<div style=\"border-left:4px solid #d97706;background:#fffbf3;padding:16px 18px;margin:26px 0;border-radius:8px\">\n<p style=\"margin:0 0 8px;color:#013366;font-weight:700;font-size:17px\">Zinc pyrithione: banned in the EU since 2022<\/p>\n<p style=\"margin:0;color:#2e3033;line-height:1.6\">Zinc pyrithione (INCI: <em>Zinc Pyrithione<\/em>) was the anti-dandruff classic for decades, and in the EU it has now gone: under Regulation (EU) 2021\/1902 the substance was classified as toxic for reproduction (CMR category 1B), and cosmetics containing zinc pyrithione had to be withdrawn from the EU market by 1 March 2022, which is why European manufacturers reformulated to piroctone olamine and climbazole. Great Britain retained the European cosmetics rules only as they stood at the end of 2020 and has set its own since, so that later EU ban does not automatically apply here. In the US the ingredient remains permitted at 0.3 to 2% in rinse-off products. If you compare products across markets, that explains why the ingredient list on one bottle reads differently from the next.<\/p>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">So what is the best shampoo for hair loss?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The best shampoo for hair loss is the one whose active ingredient fits your scalp problem, not the most expensive one and not the one with the biggest promise. For dandruff and seborrhoeic dermatitis, antifungal ingredients are the first choice; for an irritated, dry scalp, a mild shampoo with a low surfactant load.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You will deliberately not find a product ranking here. As a clinic we do not rate retail brands, and standing in front of the shelf, the ingredient list tells you more than any best-of list anyway. How to check a label in one minute is explained further down.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Caffeine shampoo for hair loss: what the studies actually show<\/h2>\n\n\n\n<div style=\"border:1px solid #cfe0f7;border-left:4px solid #0079F1;background:#f6f9fc;border-radius:8px;padding:14px 16px 15px;margin:0 0 24px\">\n<div style=\"margin:0 0 7px\"><span style=\"display:inline-block;background:#013366;color:#ffffff;font-size:11px;font-weight:700;letter-spacing:.06em;text-transform:uppercase;padding:4px 9px;border-radius:4px;vertical-align:middle\">Short answer<\/span> <span style=\"color:#013366;font-weight:700;font-size:19px;vertical-align:middle\">Not documented.<\/span><\/div>\n<p style=\"margin:0;color:#2e3033;font-size:16px;line-height:1.6\">Caffeine shampoo is among the best-selling products marketed against hair loss, yet the evidence comes almost entirely from hair follicles cultured in the lab. There is no randomised human trial with hair density as an endpoint for caffeine shampoo.<\/p>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">The most frequently cited work comes from Fischer et al. (International Journal of Dermatology, 2007): 14 follicle biopsies from the vertex region of men with androgenetic alopecia were kept in organ culture for 120 to 192 hours. Testosterone suppressed growth, and caffeine at concentrations of 0.001 and 0.005% counteracted that suppression.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A follow-up study by the same group (British Journal of Dermatology, 2014) described effects on hair shaft elongation in male and female follicles, again ex vivo. One of the mechanisms discussed is inhibition of 5-alpha reductase. That is a plausible mechanism, but not proof of efficacy in humans.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The difference that matters: in the culture dish the substance sits on the follicle continuously, while washing your hair takes minutes. Ex vivo is not in vivo, and that leap is regularly skipped over in product communication.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An honest verdict: as a mild everyday shampoo, caffeine is unproblematic, and if it makes scalp care easier for you, there is nothing against it. As a treatment for hereditary hair loss it is not documented. Anyone who waits six months on it loses six months. We have collected user reports on one well-known caffeine product in our article on Plantur 21 .<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">DHT blocker shampoo: can a shampoo block DHT?<\/h2>\n\n\n\n<div style=\"border:1px solid #cfe0f7;border-left:4px solid #0079F1;background:#f6f9fc;border-radius:8px;padding:14px 16px 15px;margin:0 0 24px\">\n<div style=\"margin:0 0 7px\"><span style=\"display:inline-block;background:#013366;color:#ffffff;font-size:11px;font-weight:700;letter-spacing:.06em;text-transform:uppercase;padding:4px 9px;border-radius:4px;vertical-align:middle\">Short answer<\/span> <span style=\"color:#013366;font-weight:700;font-size:19px;vertical-align:middle\">No.<\/span><\/div>\n<p style=\"margin:0;color:#2e3033;font-size:16px;line-height:1.6\">A DHT blocker shampoo has virtually no effect on DHT levels inside the hair follicle. Dihydrotestosterone is produced directly in the tissue, by an enzyme that a rinsed-off cleansing product does not inhibit to any relevant degree.<\/p>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">The cascade in four steps: testosterone reaches the scalp via the bloodstream. There, the enzyme 5-alpha reductase (types I and II) converts it into dihydrotestosterone. DHT binds to the androgen receptor of the dermal papilla. With every cycle, the follicle then produces a thinner, shorter hair, until only vellus fuzz is left.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What is marketed on bottles as a DHT blocker is usually saw palmetto (<em>Serenoa serrulata<\/em>), pumpkin seed oil, green tea extract, caffeine or biotin. For saw palmetto there are small oral and topical leave-in studies with methodological weaknesses; for the rinsed-off shampoo form there is no solid data. On top of that, \u201cDHT blocker\u201d is not a defined technical term but a marketing label with no fixed composition.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To date, the only demonstrable way to lower DHT is systemically. In the UK, finasteride and dutasteride are prescription-only medicines; visible results often take 6 to 12 months, and the side effect profile includes erectile dysfunction and low mood, among others. How they work is explained in our article on <a href=\"\/uk\/blog\/dht-blockers\/\">DHT blockers<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Diffuse, genetic or breakage? The distinction that decides everything<\/h2>\n\n\n\n<div style=\"border:1px solid #cfe0f7;border-left:4px solid #0079F1;background:#f6f9fc;border-radius:8px;padding:14px 16px 15px;margin:0 0 24px\">\n<div style=\"margin:0 0 7px\"><span style=\"display:inline-block;background:#013366;color:#ffffff;font-size:11px;font-weight:700;letter-spacing:.06em;text-transform:uppercase;padding:4px 9px;border-radius:4px;vertical-align:middle\">Short answer<\/span> <span style=\"color:#013366;font-weight:700;font-size:19px;vertical-align:middle\">The pattern decides.<\/span><\/div>\n<p style=\"margin:0;color:#2e3033;font-size:16px;line-height:1.6\">Whether a shampoo for hair loss can achieve anything at all depends on the type of hair loss you have. Three patterns have to be told apart: even thinning across the whole head, a receding hairline with a thinning crown, and broken hairs without a root.<\/p>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Diffuse thinning points to a cause inside the body, such as iron deficiency, the thyroid, an infection, a medicine or significant weight loss. The pattern with receding temples and a thinning crown points to the androgenetic form. Broken hairs are not hair loss at all, they are a care and styling issue. For the overview, see our article on the <a href=\"\/uk\/blog\/causes-of-hair-loss\/\">causes of hair loss<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practice, several patterns often occur at the same time. That is exactly why self-diagnosis via a search engine is unreliable, and exactly why it pays to look at the end of the hair before you buy the next product.<\/p>\n\n\n\n<style>\n@media (max-width:640px){\n.rt-table-wrap{overflow-x:visible!important;border:0!important;border-radius:0!important}\n.rt-table{min-width:0!important}\n.rt-table thead{display:none}\n.rt-table,.rt-table tbody,.rt-table tr,.rt-table td{display:block;width:100%}\n.rt-table caption{display:block;padding:0 0 12px!important}\n.rt-table tr{margin:0 0 12px;border:1px solid #dbe4f0;border-radius:10px;overflow:hidden}\n.rt-table tr:last-child{margin-bottom:0}\n.rt-table td{display:flex!important;flex-direction:column;gap:3px;padding:12px 14px!important;\nborder:0!important;border-bottom:1px solid #e3e8ef!important;background:#ffffff!important}\n.rt-table tr td:last-child{border-bottom:0!important}\n.rt-table td::before{content:attr(data-label);font-size:12px;font-weight:700;letter-spacing:.04em;\ntext-transform:uppercase;color:#5799F1}\n.rt-table td:not([data-label])::before,.rt-table td[data-label=\"\"]::before{display:none}\n}\n<\/style>\n<div class=\"rt-table-wrap\" style=\"overflow-x:auto;-webkit-overflow-scrolling:touch;margin:28px 0;border:1px solid #dbe4f0;border-radius:12px\">\n  <table class=\"rt-table\" style=\"width:100%;min-width:620px;table-layout:fixed;border-collapse:separate;border-spacing:0;font-size:15px;margin:0\">\n    <caption style=\"caption-side:top;text-align:left;color:#003366;font-weight:700;font-size:16px;line-height:1.35;padding:14px 16px 10px;background:#ffffff\">Hair breakage or hair loss?

class=\"wp-block-paragraph\">The pull test that dermatologists use is a useful addition: take a strand of about 40 to 60 hairs close to the scalp and pull slowly and evenly all the way to the tip, at several spots on the head and not right after washing your hair.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The way it is scored, though, is not consistent. Classically, a result of more than 10% of hairs pulled out, roughly 6 out of 40 to 60, counted as abnormal. McDonald et al., by contrast, found in 2017 in the Journal of the American Academy of Dermatology that in healthy volunteers a normal pull test yields no more than 2 hairs. That makes the test a rough guide at best, and it does not replace a medical examination.<\/p>\n\n\n\n<div style=\"border-left:4px solid #0079F1;background:#f6f9fc;padding:16px 18px;margin:26px 0;border-radius:8px\">\n<p style=\"margin:0 0 8px;color:#013366;font-weight:700;font-size:17px\">What we see in consultations<\/p>\n<p style=\"margin:0;color:#2e3033;line-height:1.6\">A large share of the people who write to us have already worked their way through several shampoos before their first professional assessment, without anyone ever pinning down which pattern they actually have. That costs months, and the hair loss keeps progressing in the meantime. The other order makes far more sense: first establish what you are dealing with, then decide whether any product can contribute anything at all, and which one.<\/p>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Shampoo for hair loss in women: usually the diffuse pattern<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In women, hair loss shows up diffusely more often than in men, and behind a diffuse pattern there is usually a cause inside the body that no shampoo can reach: iron deficiency, the thyroid, the period after giving birth, the menopause or a very strict diet.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The hereditary form exists in women too. According to MedlinePlus, the patient portal of the US National Library of Medicine, up to 70% of men and 40% of women are affected over the course of their lives, in women typically as a widening of the centre parting according to the Ludwig classification rather than as a receding hairline. A shampoo changes nothing about the pattern itself. More on this in our article on hair loss in women.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Realistically, a shampoo does three things for women: scalp care, treatment of flaking and itching, and less hair breakage from colouring, heat, extensions and tightly bound ponytails. With traction alopecia caused by constant pulling, the hairstyle is the treatment, not the shampoo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pregnancy and breastfeeding: be cautious with medicated shampoos, and talk to your doctor or pharmacist before using one. The heavy hair loss after giving birth, known as postpartum effluvium, is usually self-limiting and normally settles within 6 to 12 months.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the parting is getting wider or the thinning continues over months, blood tests should come before the next product purchase. What matters most are ferritin, thyroid values and vitamin D. For ferritin, various target values between 30 and 70 \u00b5g\/L are cited; there is no consistently agreed threshold for hair loss, and iron should never be taken without a medical diagnosis because of the risk of overload. We have separate articles on the two most common triggers: <a href=\"\/uk\/blog\/iron-deficiency-hair-loss\/\">iron deficiency and hair loss<\/a> as well as <a href=\"\/uk\/blog\/thyroid-hair-loss\/\">hair loss caused by the thyroid<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Shampoo for hair loss in men: usually the genetic pattern<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In the vast majority of men it is the genetic pattern, which is precisely the form a shampoo can do nothing about. A population-based study of 1,005 men found a prevalence of around 58% between the ages of 30 and 50, with a marked increase at older ages. Figures like these vary considerably depending on the study population, but the direction is unambiguous.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The sensible role of a shampoo is therefore that of a companion, not a treatment: keeping the scalp free of flaking, itching and inflammation so that an effective therapy can work on calm skin. That is not glamorous, but it is the honest contribution a wash-off product can make.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to spot a trustworthy shampoo for hair loss<\/h2>\n\n\n\n<div style=\"border:1px solid #cfe0f7;border-left:4px solid #0079F1;background:#f6f9fc;border-radius:8px;padding:14px 16px 15px;margin:0 0 24px\">\n<div style=\"margin:0 0 7px\"><span style=\"display:inline-block;background:#013366;color:#ffffff;font-size:11px;font-weight:700;letter-spacing:.06em;text-transform:uppercase;padding:4px 9px;border-radius:4px;vertical-align:middle\">Short answer<\/span> <span style=\"color:#013366;font-weight:700;font-size:19px;vertical-align:middle\">By three features.<\/span><\/div>\n<p style=\"margin:0;color:#2e3033;font-size:16px;line-height:1.6\">A trustworthy shampoo for hair loss names its active ingredient and its concentration, promises effects on the scalp rather than hair growth, and does not advertise with before-and-after photos.<\/p>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">The legal framework explains why labels sound the way they do. In the UK a shampoo is normally a cosmetic and not a medicine: it falls under the UK Cosmetics Regulation, the European cosmetics rules carried over into British law after the UK left the EU. Those rules cover products applied to the body for cleansing or beautifying, and they are enforced by the Office for Product Safety and Standards. The moment a product claims to treat a condition, it counts as a medicine and needs a licence of its own.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On top of that, the Advertising Standards Authority acts against misleading advertising on the basis of the CAP Code, whose rule 3.1 states that marketing communications must not materially mislead or be likely to do so: claims have to be truthful, backed by verifiable evidence and must not mislead. That is why bottles almost never say \u201cstops hair loss\u201d but rather \u201cfor thicker, fuller-looking hair\u201d or \u201chelps reduce breakage\u201d. Once you have understood that, you read every label differently.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cClinically tested\u201d, by the way, only means that testing happened. It says nothing about how many people took part, for how long, against what it was compared and what came out in the end. If those four details are missing, the phrase is decoration.<\/p>\n\n\n\n<style>\n@media

class=\"wp-block-heading\">What does \u201cmild shampoo\u201d actually mean? The surfactants on the label<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You do not recognise a mild shampoo by the marketing word \u201cgentle\u201d but by the surfactant that does the cleansing. Surfactants appear in the INCI list right after <em>Aqua<\/em>, because the list is sorted by descending amount. Anyone who looks there knows in ten seconds how aggressively a product cleanses.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The classic sulfates count as strong cleansers: <em>Sodium Lauryl Sulfate<\/em> and <em>Sodium Laureth Sulfate<\/em>. They foam heavily and can further dry out a skin barrier that is already irritated. Sugar-based and amino-acid-based surfactants, on the other hand, count as mild, such as <em>Coco Glucoside<\/em>, <em>Sodium Cocoyl Isethionate<\/em>, <em>Disodium Cocoamphodiacetate<\/em>, <em>Sodium Cocoyl Glutamate<\/em> or <em>Cocamidopropyl Betaine<\/em>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One important point of context: sulfates do not cause hair loss, they are a question of comfort on a sensitive or flaking scalp. And you do not swap an active-ingredient shampoo containing ketoconazole or selenium sulfide for a mild product, you use the mild one between the active-ingredient days.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">General sale, pharmacy or prescription: where the difference really lies<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The difference is not a question of price but of regulatory status. On supermarket and high-street shelves you will mostly find cosmetics, alongside general sale list (GSL) medicines, which may be sold anywhere. Behind the pharmacy counter come the pharmacy medicines (P), which need no prescription but do need a pharmacist, and the prescription-only medicines (POM): with a declared active ingredient, a defined concentration, a patient information leaflet and a licensed indication.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ketoconazole is the textbook example: the 2% shampoo is a licensed medicine in the P category, so the pharmacy can hand it over without a prescription, while topical minoxidil is on general sale and finasteride tablets are prescription-only. Conversely, an expensive cosmetic shampoo bought at a pharmacy is still a cosmetic. The rule of thumb is therefore: what counts is the status on the pack, not the point of sale and not the price.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Using a shampoo for hair loss correctly: washing frequency, contact time, combinations<\/h2>\n\n\n\n<div style=\"border:1px solid #cfe0f7;border-left:4px solid #0079F1;background:#f6f9fc;border-radius:8px;padding:14px 16px 15px;margin:0 0 24px\">\n<div style=\"margin:0 0 7px\"><span style=\"display:inline-block;background:#013366;color:#ffffff;font-size:11px;font-weight:700;letter-spacing:.06em;text-transform:uppercase;padding:4px 9px;border-radius:4px;vertical-align:middle\">Short answer<\/span> <span style=\"color:#013366;font-weight:700;font-size:19px;vertical-align:middle\">3 to 5 minutes, twice a week.<\/span><\/div>\n<p style=\"margin:0;color:#2e3033;font-size:16px;line-height:1.6\">Active-ingredient shampoos need contact time: the labelling for ketoconazole and selenium sulfide shampoos specifies 3 to 5 minutes and, in the acute phase, two applications per week. Lathering briefly and rinsing straight away renders even the best-documented ingredient useless.<\/p>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">How often you wash depends on your scalp, not on the amount of hair in the plughole. With a greasy, flaking scalp, washing more often is actually part of the treatment, because it reduces the sebum that Malassezia feeds on. So what matters is not how often you wash, but what you wash with and how long it stays on.<\/p>\n\n\n\n<style>\n@media (max-width:640px){\n.rt-table-wrap{overflow-x:visible!important;border:0!important;border-radius:0!important}\n.rt-table{min-width:0!important}\n.rt-table thead{display:none}\n.rt-table,.rt-table tbody,.rt-table tr,.rt-table td{display:block;width:100%}\n.rt-table caption{display:block;padding:0 0 12px!important}\n.rt-table tr{margin:0 0 12px;border:1px solid #dbe4f0;border-radius:10px;overflow:hidden}\n.rt-table tr:last-child{margin-bottom:0}\n.rt-table td{display:flex!important;flex-direction:column;gap:3px;padding:12px 14px!important;\nborder:0!important;border-bottom:1px solid #e3e8ef!important;background:#ffffff!important}\n.rt-table tr td:last-child{border-bottom:0!important}\n.rt-table td::before{content:attr(data-label);font-size:12px;font-weight:700;letter-spacing:.04em;\ntext-transform:uppercase;color:#5799F1}\n.rt-table td:not([data-label])::before,.rt-table td[data-label=\"\"]::before{display:none}\n}\n<\/style>\n<div class=\"rt-table-wrap\" style=\"overflow-x:auto;-webkit-overflow-scrolling:touch;margin:28px 0;border:1px solid #dbe4f0;border-radius:12px\">\n  <table class=\"rt-table\" style=\"width:100%;min-width:620px;table-layout:fixed;border-collapse:separate;border-spacing:0;font-size:15px;margin:0\">\n    <caption style=\"caption-side:top;text-align:left;color:#003366;font-weight:700;font-size:16px;line-height:1.35;padding:14px 16px 10px;background:#ffffff\">A realistic timeline: what a shampoo for hair loss can achieve when, and what it cannot.<\/caption>\n    <thead>\n      <tr>\n        <th style=\"width:22%;background:#003366;color:#ffffff;font-weight:700;text-align:left;vertical-align:middle;padding:13px 16px;font-size:15px;line-height:1.4;border:0;overflow-wrap:break-word\">Time frame<\/th>\n        <th style=\"background:#003366;color:#ffffff;font-weight:700;text-align:left;vertical-align:middle;padding:13px 16px;font-size:15px;line-height:1.4;border:0;overflow-wrap:break-word\">What realistically happens<\/th>\n        <th style=\"background:#003366;color:#ffffff;font-weight:700;text-align:left;vertical-align:middle;padding:13px 16px;font-size:15px;line-height:1.4;border:0;overflow-wrap:break-word\">How you measure it<\/th>\n      <\/tr>\n    <\/thead>\n    <tbody>\n      <tr>\n        <td data-label=\"Time frame\" style=\"background:#ffffff;color:#003366;font-weight:700;text-align:left;vertical-align:top;padding:13px 16px;font-size:15px;line-height:1.55;border:0;border-bottom:1px solid #e3e8ef;overflow-wrap:break-word\">Week 1\u20132<\/td>\n        <td data-label=\"What realistically happens\" style=\"background:#ffffff;color:#22303e;font-weight:400;text-align:left;vertical-align:top;padding:13px 16px;font-size:15px;line-height:1.55;border:0;border-bottom:1px solid #e3e8ef;overflow-wrap:break-word\">With an antifungal active ingredient, itching and flaking usually decrease.

Use a mild shampoo between applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Baby shampoo<\/strong> is mild, but it is not a remedy for hair loss. Mild surfactants protect the skin barrier and cause less irritation. On a follicle that is shrinking under the influence of DHT, they change nothing. Mild means gentle, not effective.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Solid shampoo bars<\/strong> make ecological sense and come with two practical catches when hair loss is the issue. Classic soap-based bars sit at a pH of around 9 to 10, while the scalp&#8217;s acid mantle is at pH 4.5 to 5.5; in hard water, soap residue can form and roughen the cuticle. Modern syndet bars with an adjusted pH largely avoid this.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The second catch is mechanical: rubbing the bar across the scalp under pressure puts unnecessary strain on hair and skin and can encourage breakage. Better to work up a lather in your hands and spread the foam.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Combining with topical minoxidil:<\/strong> wash first, let the scalp dry completely, then apply. The NHS patient information explicitly advises against putting minoxidil on wet skin. So not at the same time and not straight out of the shower.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Combining with prescription products:<\/strong> if a dermatologist has given you a solution or a foam, discuss any addition or switch beforehand. Salicylic acid increases the absorption of other topicals, and prescribed products come with their own application schedules, which you should not add to or stop on your own.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Silicones and sulfates<\/strong> are the perennial forum topic. Silicones coat the hair shaft, make the hair look fuller and do not cause hair loss. Sulfates (INCI <em>Sodium Laureth Sulfate<\/em> and <em>Sodium Lauryl Sulfate<\/em>) cleanse vigorously and can further dry out an irritated barrier. That is a reason for itching, not a reason for losing follicles. How a hair grows and is shed in the first place is explained in our article on the hair cycle.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can a shampoo cause hair loss?<\/h2>\n\n\n\n<div style=\"border:1px solid #cfe0f7;border-left:4px solid #0079F1;background:#f6f9fc;border-radius:8px;padding:14px 16px 15px;margin:0 0 24px\">\n<div style=\"margin:0 0 7px\"><span style=\"display:inline-block;background:#013366;color:#ffffff;font-size:11px;font-weight:700;letter-spacing:.06em;text-transform:uppercase;padding:4px 9px;border-radius:4px;vertical-align:middle\">Short answer<\/span> <span style=\"color:#013366;font-weight:700;font-size:19px;vertical-align:middle\">As a rule, no.<\/span><\/div>\n<p style=\"margin:0;color:#2e3033;font-size:16px;line-height:1.6\">A normal shampoo does not cause hair loss. What it can trigger is a contact allergy or scalp irritation, and that can contribute to hair loss indirectly, through inflammation and scratching.<\/p>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">The usual culprits are preservatives such as methylisothiazolinone, fragrances, hair dyes and bleaching agents, plus very harsh surfactants on an already damaged barrier. Typical signs are redness, burning, weeping and flaking that disappear again after a product switch.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does washing your hair every day cause hair loss?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No, washing your hair daily does not cause hair loss. According to the American Academy of Dermatology, shedding 50 to 100 hairs a day is normal. Those hairs were already in the resting phase; washing merely releases them from the head, it does not push any hair into shedding early.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The error is one of perception. If you only wash every three days, you see three days&#8217; worth all at once in the plughole and mistake it for a sudden worsening. Washing less often just lets the telogen hairs pile up, it does not prevent them.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If your scalp is greasy and flaking, there is even more to be said for washing frequently: it reduces the sebum that Malassezia feeds on and is therefore part of treating dandruff. What matters then is a mild base product on the days between the active-ingredient applications.<\/p>\n\n\n\n<div style=\"border-left:4px solid #c0392b;background:#fdf5f4;padding:16px 18px;margin:26px 0;border-radius:8px\">\n<p style=\"margin:0 0 8px;color:#013366;font-weight:700;font-size:17px\">These signs belong with a doctor, not in the shampoo aisle<\/p>\n<ul style=\"margin:0;padding:0;color:#2e3033;list-style:none;line-height:1.6\">\n<li style=\"position:relative;padding:3px 0 3px 20px\"><span style=\"position:absolute;left:0;top:3px;color:#c0392b;font-weight:700\">&bull;<\/span>persistent pain or burning of the scalp<\/li>\n<li style=\"position:relative;padding:3px 0 3px 20px\"><span style=\"position:absolute;left:0;top:3px;color:#c0392b;font-weight:700\">&bull;<\/span>pustules or weeping areas<\/li>\n<li style=\"position:relative;padding:3px 0 3px 20px\"><span style=\"position:absolute;left:0;top:3px;color:#c0392b;font-weight:700\">&bull;<\/span>shiny, bald patches with no visible follicular openings, a sign of scarring alopecia<\/li>\n<li style=\"position:relative;padding:3px 0 3px 20px\"><span style=\"position:absolute;left:0;top:3px;color:#c0392b;font-weight:700\">&bull;<\/span>sudden, circular hair loss<\/li>\n<li style=\"position:relative;padding:3px 0 3px 20px\"><span style=\"position:absolute;left:0;top:3px;color:#c0392b;font-weight:700\">&bull;<\/span>hair loss in children<\/li>\n<\/ul>\n<p style=\"margin:12px 0 0;color:#2e3033;line-height:1.6\">When you see signs like these, time is what decides the outcome. Switching products is not enough here; the scalp needs a dermatological examination.<\/p>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">When the shampoo is not enough: what demonstrably works against hereditary hair loss<\/h2>\n\n\n\n<div style=\"border:1px solid #cfe0f7;border-left:4px solid #0079F1;background:#f6f9fc;border-radius:8px;padding:14px 16px 15px;margin:0 0 24px\">\n<div style=\"margin:0 0 7px\"><span style=\"display:inline-block;background:#013366;color:#ffffff;font-size:11px;font-weight:700;letter-spacing:.06em;text-transform:uppercase;padding:4px 9px;border-radius:4px;vertical-align:middle\">Short answer<\/span> <span style=\"color:#013366;font-weight:700;font-size:19px;vertical-align:middle\">Minoxidil and prescription medicines.<\/span><\/div>\n<p style=\"margin:0;color:#2e3033;font-size:16px;line-height:1.6\">In the UK, topical minoxidil and doctor-prescribed medicines have the most solid data behind them for androgenetic hair loss. Both stay on the scalp or work systemically, and neither of them is a product that gets rinsed out.<\/p>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Topical minoxidil is on general sale in 2% and 5% formulations, so you can buy it without a prescription. According to the NHS patient information, an effect becomes apparent after about 3 to 6 months, and the application has to be continued permanently, otherwise the effect recedes. Benefits, limits and side effects are covered in our article on <a href=\"\/uk\/blog\/minoxidil-hair-loss\/\">minoxidil for hair loss<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">5-alpha reductase inhibitors are prescription-only medicines and belong in a doctor&#8217;s hands, including a proper conversation about the side effect profile and the fact that treatment for hereditary hair loss is not always available on the NHS. Visible results are often only to be expected after 6 to 12 months. What lies behind them is explained in our article on <a href=\"\/uk\/blog\/dht-blockers\/\">DHT blockers<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Before any of that, though, comes step zero: establishing the cause. If the thinning is diffuse, it is worth checking ferritin, thyroid values and vitamin D before buying any product at all. Which values make sense to measure is covered in our article on the blood test for hair loss.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where to go from here: the next sensible step<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When it comes to shampoo for hair loss, the next sensible step is not another bottle but a straight answer to one question: which pattern do you have, diffuse thinning, the genetic pattern or hair breakage? That question decides whether a product can contribute anything at all. Two routes lead there.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If an internal cause is suspected, meaning with diffuse thinning, the route runs through your GP or a dermatologist: blood values such as ferritin, TSH and vitamin D can only be checked there, and if pain, pustules or bald patches are involved, a dermatological examination is needed anyway.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And to be transparent about our own role: we are a hair clinic, but we do not sell shampoos. What we do offer is a <a href=\"\/uk\/hair-analysis\/\">free hair analysis<\/a>, meaning a visual assessment of your pattern from your photos, with no predetermined outcome and no obligation to book a treatment afterwards. It does not replace a medical blood test, and where a diffuse effluvium is behind the shedding, a hair transplant is explicitly not the answer.<\/p>\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-fe48e5de wp-block-buttons-is-layout-flex\" style=\"justify-content:center;margin-bottom:48px\"><div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" style=\"background-color:#0079F1;color:#ffffff;border-radius:8px;padding:15px 36px;font-weight:700;font-size:17px;display:flex;justify-content:center;align-items:center\" href=\"\/uk\/hair-analysis\/\">Start your free hair analysis<\/a><\/div><\/div>\n\n\n<h2 class=\"wp-block-heading\">Frequently asked questions about shampoo for hair loss<\/h2>\n\n\n\n<div style=\"margin:8px 0 24px\">\n<div style=\"border:1px solid #e3e8ef;border-radius:10px;padding:16px;margin-bottom:12px\">\n<p style=\"margin:0 0 6px;color:#013366;font-weight:600\">How long does a shampoo for hair loss have to stay on?<\/p>\n<p style=\"margin:0;color:#2e3033\">The labelling for ketoconazole and selenium sulfide shampoos specifies 3 to 5 minutes of contact time before rinsing, twice a week in the acute phase. Lathering briefly and rinsing straight away renders even the best-documented ingredient useless. A short timer on your phone helps more than any additional product.<\/p>\n<\/div>\n<div style=\"border:1px solid #e3e8ef;border-radius:10px;padding:16px;margin-bottom:12px\">\n<p style=\"margin:0 0 6px;color:#013366;font-weight:600\">Do I have to use an active-ingredient shampoo permanently?<\/p>\n<p style=\"margin:0;color:#2e3033\">With chronic seborrhoea, as a rule yes. After the treatment phase of 2 to 4 weeks comes maintenance with one application per week or every two weeks, otherwise flaking and itching come back. The active ingredient treats the condition, it does not remove the predisposition behind it.<\/p>\n<\/div>\n<div style=\"border:1px solid #e3e8ef;border-radius:10px;padding:16px;margin-bottom:12px\">\n<p style=\"margin:0 0 6px;color:#013366;font-weight:600\">Why does my active-ingredient shampoo smell so medicinal?<\/p>\n<p style=\"margin:0;color:#2e3033\">The characteristic smell comes from the antifungal ingredients themselves, and it is particularly noticeable with selenium sulfide. It is not a quality defect, and you can soften it by using a mild shampoo on the days in between and applying conditioner only to lengths and ends.<\/p>\n<\/div>\n<div style=\"border:1px solid #e3e8ef;border-radius:10px;padding:16px;margin-bottom:12px\">\n<p style=\"margin:0 0 6px;color:#013366;font-weight:600\">Does baby shampoo help with hair loss?<\/p>\n<p style=\"margin:0;color:#2e3033\">No. Baby shampoo is mild and barely irritates the scalp, which is pleasant on irritated skin. On a follicle that is shrinking under the influence of DHT, it changes nothing. Mild means gentle, not effective.<\/p>\n<\/div>\n<div style=\"border:1px solid #e3e8ef;border-radius:10px;padding:16px;margin-bottom:12px\">\n<p style=\"margin:0 0 6px;color:#013366;font-weight:600\">Are solid shampoo bars suitable for hair loss?<\/p>\n<p style=\"margin:0;color:#2e3033\">They are possible, with two caveats.
