Creatine is the most studied, most effective, most boringly safe supplement in the gym — and it’s dogged by one persistent fear: that it’ll cost you your hair. The short version: the evidence says you can relax.
Where the Myth Came From
One study, 2009. A group of college rugby players took creatine and showed a rise in DHT — the hormone that shrinks follicles in people genetically prone to pattern baldness. Nobody had actually measured whether creatine affects hair. They measured a hormone and assumed the rest.
What the New Research Actually Found
In 2025, a 12-week randomized, placebo-controlled trial had men take 5g of creatine daily while measuring hair itself — density, follicle count, thickness. Result: no significant difference in DHT, and no difference in any hair measure versus placebo.
Caveats: it was small (38 men) over 12 weeks, and didn’t measure DHT activity directly at the scalp. But it’s real evidence against the myth.
So Who Should Actually Worry?
If you carry the genes for male pattern baldness, your follicles are sensitive to DHT no matter where it comes from — that’s the actual driver. Even in the worst-case reading, any creatine effect is trivial next to your genetics.
The Bottom Line
There’s no good evidence that creatine causes hair loss. Keep taking it, train hard, and if balding runs in your family, fight that fight where it’s actually happening.
