Does Creatine Cause Hair Loss? The DHT Question

If you’ve spent any time in fitness forums, you’ve seen the warning: creatine causes hair loss. It’s one of the most repeated worries about the most studied sports supplement on the shelf. So does creatine cause hair loss — or is this a case of one study turning into a decade of internet folklore? Here’s the honest, evidence-based answer.

Where the creatine hair loss fear comes from

The entire creatine-balding story traces back to a single 2009 study. Researchers had 20 college rugby players load 25 g/day of creatine for 7 days, then take 5 g/day for 14 days. They measured the hormone DHT (dihydrotestosterone) — which rose about 56% after the loading phase and stayed roughly 40% above baseline during maintenance.

DHT matters here because it’s the androgen most associated with male-pattern hair loss in people who are genetically prone. So a jump in DHT sounds alarming. But there’s a critical catch.

What the DHT study actually showed

Beyond not measuring hair, the 2009 study had a notable quirk: the creatine group started with DHT that was already 23% lower than the placebo group (0.98 vs 1.26 nmol/L). So part of the “increase” brought a group up from a lower starting point. Total testosterone didn’t rise at all, and the DHT finding has never been replicated in the years since.

A 2021 ISSN-affiliated review weighed this against the broader literature. Across 12 other studies (doses 3–25 g/day, lasting 6 days to 12 weeks) that examined androgens, 10 showed no change and 2 showed only small, within-normal-range increases. The review’s conclusion is blunt: the current body of evidence “does not indicate that creatine supplementation increases total testosterone, free testosterone, DHT or causes hair loss/baldness.”

The first study to actually look at hair follicles

For years the honest answer was “no direct evidence either way on hair.” That changed in 2025, when Lak et al. ran the first randomized trial to directly examine hair follicles during creatine use. It was a 12-week, double-blind RCT with 38 male completers (19 creatine, 19 placebo) at the standard 5 g/day maintenance dose.

The result: no significant differences in DHT (p=0.70), the DHT:testosterone ratio (p=0.44), total testosterone, or free testosterone. And on the hair side — which the 2009 study never touched — there were no differences in hair count, density, follicular units, anagen/telogen phases, terminal-vs-vellus ratio, or hair thickness (all p>0.05). The authors describe it as “strong evidence against the claim that creatine contributes to hair loss.”

So is creatine a steroid that wrecks your hairline?

No — and this is worth separating clearly. Anabolic steroids are synthetic testosterone analogues that bind androgen receptors to drive muscle growth. Creatine is chemically unrelated: it works by helping regenerate ATP (your cells’ energy currency) through the phosphocreatine system, not by acting on hormones. It’s regulated as a dietary supplement and is not banned by WADA, the IOC, or the NCAA. The mechanism behind creatine’s actual, well-supported benefits — modest gains in strength and lean mass alongside resistance training — has nothing to do with androgen-driven hair loss.

The bottom line

Does creatine cause hair loss? Based on the evidence available, there is no direct support for it. The entire creatine-DHT-balding chain rests on one 2009 study that measured a transient hormone shift and never looked at hair — and that DHT finding has never been replicated. The first trial to actually examine follicles found no effect on hormones or hair. Vantra is simply 5 g/day of creatine monohydrate (Creapure), split into Dawn (AM, citrus) and Dusk (PM, wild berry) — the same studied dose used in the research above. As always, if you have a personal or family history of hair loss or any health concern, it’s reasonable to check with your doctor.
