In short: where do we stand today?<\/p>\n
- \n
- For men with no genetic predisposition to hereditary hair loss, creatine is considered safe according to the current evidence. There is no convincing proof that it costs you any hair.<\/li>\n
- For men with a family history of hair loss, a theoretical residual uncertainty remains. One old study showed a rise in DHT, but it was never confirmed.<\/li>\n
- The first genuine hair RCT, in 2025, found neither a rise in DHT nor any change in hair density over twelve weeks.<\/li>\n
- Anyone who already has hereditary hair loss and wants to take creatine is on the safe side with a 5-alpha-reductase inhibitor such as finasteride for DHT protection.<\/li>\n<\/ul>\n<\/div>\n\n\n\n
If you’re already losing hair, the cause is very probably not your creatine but a hereditary predisposition. When in doubt, have your hair situation assessed by a professional before you drop supplements out of panic.<\/p>\n\n\n\n
What exactly is creatine, and how does it work?<\/h2>\n\n\n\n
Creatine isn’t some exotic chemical out of a lab. It’s a substance your own body produces. Your liver, your kidneys and your pancreas make around one to two grams of it every day, from the amino acids arginine, glycine and methionine. On top of that comes creatine from food, above all from meat and fish. If you eat an omnivorous diet, you take in another one to two grams a day this way. That’s why vegetarians and vegans naturally have lower stores.<\/p>\n\n\n\n
In the muscle, creatine is stored as phosphocreatine. During short, intense efforts such as a heavy set or a sprint, this phosphocreatine delivers its phosphate group in a flash, turning ADP back into ATP, the cell’s energy currency. That’s the whole trick: more available ATP for maximum effort. There’s no hormonal mechanism anywhere in it.<\/p>\n\n\n\n
And this is the crucial point where most of the misconceptions fall apart. Creatine is not testosterone, not a steroid, not a prohormone. It isn’t on the WADA doping list. It’s the most thoroughly studied legal sports supplement in the world, backed by well over five hundred studies. Mixing it up with anabolic steroids is where the hair loss myth really takes root, and we’ll come back to that distinction in detail later.<\/p>\n\n\n\n
Where the myth that creatine causes hair loss comes from<\/h2>\n\n\n\n
Almost every warning about creatine and hair loss can be traced back to a single piece of work. In 2009, a South African research group led by Johann van der Merwe studied twenty college rugby players in a randomised, double-blind, placebo-controlled design. The participants took a loading phase of 25 grams of creatine a day for seven days, followed by a maintenance dose of 5 grams for two weeks.<\/p>\n\n\n\n
The result made headlines: after the loading phase, DHT was 56 percent above baseline, and after the maintenance phase still 33 percent above it. The ratio of DHT to testosterone also rose markedly, by 36 and 22 percent respectively. Free and total testosterone, by contrast, did not change.<\/p>\n\n\n\n
DHT, or dihydrotestosterone, is regarded as the central driver of hereditary hair loss. A headline like “creatine raises DHT by 56 percent” spreads on its own. What almost always gets lost is the detail underneath it: the absolute values rose from 0.98 to 1.26 nanomoles per litre. Both figures sit squarely within the normal physiological range. Yet from that single finding, the firm belief that creatine makes you go bald has grown up over the years.<\/p>\n\n\n\n
Why the study doesn’t support the creatine hair loss myth<\/h2>\n\n\n\n
The Van der Merwe study was an interesting signal. It was never a solid answer. Read it closely and you run into a whole series of weaknesses.<\/p>\n\n\n\n
- \n
- A tiny sample.<\/strong> Twenty participants are enough for an initial signal, not for a general statement about millions of creatine users.<\/li>\n
- Not a single hair was measured.<\/strong> There was no measurement of hair density, no phototrichogram, no follicle count. The leap from “DHT went up” to “causes hair loss” simply isn’t supported by the data.<\/li>\n
- Only three weeks.<\/strong> Hereditary hair loss develops over months and years. Three weeks of observation tell you next to nothing about it.<\/li>\n
- A skewed starting point.<\/strong> The creatine group began with DHT around 23 percent lower than the placebo group. A rise to a normal level looks more dramatic as a percentage than it really is.<\/li>\n
- All within the normal range.<\/strong> The DHT values stayed within the physiological span throughout. There was no abnormal spike.<\/li>\n
- The wrong measuring site.<\/strong> DHT was measured in the blood, not at the scalp. For hereditary hair loss, what counts is the DHT right at the follicle.<\/li>\n
- The training factor.<\/strong> Heavy strength training, especially compound lifts like squats or deadlifts, raises testosterone and DHT for a short time anyway. In a group of rugby players mid-season, it’s almost impossible to separate cleanly what came from the creatine and what came from the training itself.<\/li>\n
- Never confirmed again.<\/strong> In more than fifteen years, not a single follow-up study has reproduced this DHT finding, not even the same group’s own follow-up work in 2010.<\/li>\n<\/ul>\n\n\n\n
What the study explicitly did not show<\/h3>\n\n\n\n
It’s worth drawing this distinction cleanly. The study did not show that creatine causes hair loss. It did not show that DHT levels rise above the normal range. It did not show that the effect persists with longer use, nor did it make that effect reproducible in any other group. What it did show was a temporary, statistically notable rise in the DHT-to-testosterone ratio in a small, very specific group over three weeks. Between that finding and the claim “creatine makes you bald” lies a whole world.<\/p>\n\n\n\n
What the research on creatine and hair loss has shown since<\/h2>\n\n\n\n
Science didn’t stand still after 2009. Quite the opposite. A large review article by Antonio and colleagues from 2021 brought together thirteen studies on creatine, testosterone and DHT. The result: in ten of the thirteen studies, neither testosterone nor DHT changed. In the remaining two, minimal increases appeared with no practical significance. The authors state plainly that the evidence does not show creatine raising testosterone, free testosterone or DHT, nor triggering hair loss. An updated version in 2024 reached the same verdict.<\/p>\n\n\n\n
As far back as 2007, work by Cribb and colleagues had shown that short-term creatine intake doesn’t change the hormonal response to strength training, neither for testosterone nor for cortisol or growth hormone. So why does the myth hold on so stubbornly? Because one alarming figure sticks in the mind better than twelve unremarkable follow-up studies. And because hair loss in genetically predisposed men tends to begin at exactly the age when many start training and start taking creatine. The wrong conclusion is easy to reach.<\/p>\n\n\n\n
Creatine and hair loss in the 2025 RCT: measured at the hair itself for the first time<\/h2>\n\n\n\n
In 2025 the Journal of the International Society of Sports Nutrition published the most informative work on the subject so far, carried out by Lak, Antonio, Tinsley and further colleagues. It carries the unmistakable title “Does creatine cause hair loss?”. Forty-five resistance-trained men aged between 18 and 40 took either 5 grams of creatine monohydrate or 5 grams of maltodextrin as a placebo over twelve weeks. Thirty-eight completed the study.<\/p>\n\n\n\n
What made it special lay in the measurement. Instead of only determining hormone levels in the blood, the researchers looked at the scalp directly. They used the FotoFinder system, a phototrichogram method with polarised light and dermoscopic magnification, assessed by certified dermatologists. They measured hair density, the number of hair follicle units and cumulative hair thickness, along with serum DHT plus free and total testosterone.<\/p>\n\n\n\n
The result was clear. No significant difference in DHT levels between the groups. No change in the DHT-to-testosterone ratio. And above all: no difference in hair density, follicle count or hair thickness. It’s the first study anywhere in the world to examine the hair follicle itself after creatine intake, rather than relying on hormones as an indirect stand-in.<\/p>\n\n\n\n

An overview of the evidence on creatine and hair loss.<\/figcaption><\/figure>\n\n\n\n Honesty also means naming the limitations. The American Hair Loss Association praised the study for exactly that, while at the same time pointing to three open questions: DHT was measured in the blood, not at the scalp. The participants were not specifically pre-selected for hereditary risk. And twelve weeks is a short stretch measured against the years-long course of hereditary hair loss. In short: no evidence of hair loss is not the same as a final all-clear for men at high genetic risk. Even so, it remains the strongest evidence we have to date, and it speaks clearly against the myth.<\/p>\n\n\n\n
