Does Creatine Cause Hair Loss?

The myth and the verdict

The myth is simple: creatine raises DHT, and DHT causes male pattern baldness, so creatine makes you lose hair. The verdict is false as a demonstrated claim. Creatine has not been shown in human trials to cause hair loss or baldness. The concern comes largely from one small 2009 trial in college aged male rugby players that measured blood hormones over three weeks, not hair loss.1

That distinction matters. Hair loss is not the same outcome as a short term change in a blood hormone. Androgenetic alopecia involves genetic susceptibility, androgen signaling at the follicle, follicle miniaturization, and time. A three week DHT study can raise a question. It cannot prove baldness.

What the trial evidence actually shows

The study that started the worry was a double blind, placebo controlled crossover trial by van der Merwe, Brooks, and Myburgh. Twenty college aged rugby players took creatine for three weeks: 25 grams per day during a seven day loading phase, then 5 grams per day for 14 days. The researchers reported that DHT increased after loading and remained above baseline during maintenance, while testosterone did not increase in the same way.1

That finding is the kernel of the myth. It is also narrower than the internet version. The study did not measure hair density, hair count, shedding, scalp DHT, follicle miniaturization, dermatologist diagnosed alopecia, or long term baldness. It was not designed to answer whether creatine causes hair loss.1

The more direct evidence now points the other way. A 2025 randomized controlled trial tested 5 grams per day of creatine monohydrate versus placebo for 12 weeks in healthy resistance trained men aged 18 to 40. Forty five men were randomized and 38 completed the study. Researchers measured total testosterone, free testosterone, DHT, the DHT to testosterone ratio, and hair follicle outcomes using Trichogram testing and FotoFinder measures including hair density, follicular unit count, and cumulative hair thickness.2

The result was negative for the myth. There were no group by time interactions for DHT, DHT to testosterone ratio, or any measured hair growth parameter. In plain English: the creatine group did not diverge from placebo in the hormone pattern that people worry about, and it did not show worse measured hair outcomes over 12 weeks.2

A 2021 review from the International Society of Sports Nutrition also addressed the misconception directly. It noted that the DHT concern traces back to the 2009 study and that most investigations of creatine and testosterone related hormones have not shown increases in total testosterone, free testosterone, DHT, or hair loss outcomes that would support the claim.³

The mechanism is plausible, but the leap is too large

The reason the myth feels credible is that DHT is not irrelevant. DHT is involved in androgenetic alopecia, especially in genetically susceptible follicles. Drugs such as finasteride and dutasteride work by inhibiting 5 alpha reductase, the enzyme that converts testosterone to DHT.⁴

But plausible biology is not the same as proof of harm. The claim requires several links to hold: creatine must reliably raise DHT, that rise must occur in the scalp or meaningfully affect follicle androgen signaling, susceptible follicles must miniaturize faster, and measurable hair loss must follow. Current human evidence does not establish that chain.

The 2009 study raised a serum DHT signal in a small athlete sample after a loading protocol.1 The 2025 trial, using a common daily dose, did not replicate a DHT increase and did not find worse hair metrics.2 That does not prove creatine can never matter for any genetically susceptible person over years. It does mean the confident claim that creatine causes baldness is ahead of the evidence.

Why the myth persists

The myth persists because it has the perfect ingredients: one quotable hormone study, a familiar supplement, a visible fear, and a mechanism people can explain in one sentence. Social media compresses that into “creatine raises DHT,” then further compresses it into “creatine makes you bald.” The second statement is not what the study showed.

Marketing also keeps the concern alive. Hair loss clinics, supplement brands, and fitness influencers all benefit from content that sounds protective or contrarian. A cautious sentence about DHT becomes a headline about hairlines. Once the association is repeated enough, absence of proof starts to feel like a coverup rather than a normal evidence gap.

Anecdotes add fuel. Many people start creatine in late adolescence or early adulthood, the same period when androgenetic hair loss often first becomes noticeable in genetically prone men. If hair thinning begins after starting creatine, the timing feels persuasive. But timing alone cannot separate creatine from genetics, age, stress, dieting, illness, medications, or normal progression of pattern hair loss.

What is true nearby

There is a real truth near the myth: DHT matters in pattern hair loss, and people who are already thinning should take new shedding seriously. If your hairline is changing, the most useful step is not stopping every supplement one by one. It is getting a dermatology evaluation, because pattern hair loss, telogen effluvium, iron deficiency, thyroid issues, and inflammatory scalp conditions need different responses.

There is also a practical creatine truth: loading is optional. The 2009 study used 25 grams per day for a week before maintenance.1 Many people use 3 to 5 grams per day without loading, which gradually saturates muscle creatine stores and avoids the dramatic short term dosing phase that anchors much of the hair loss fear.³

So the clean answer is this: creatine is not proven to cause hair loss. The one DHT study raised a reasonable question. The direct human trial did not support the fear. If you value creatine for strength or training, current evidence does not justify avoiding it because of baldness claims.
