Does Creatine Cause Hair Loss?

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.

How Creatine Is Supposed to Affect DHT

The worry traces back to one 2009 study of college rugby players. After a week of creatine loading, their DHT levels rose by about 50% while staying within the normal range. Because DHT drives pattern hair loss, the internet joined the dots: creatine raises DHT, so creatine causes baldness.

The problem is that the study never measured hair at all. It was small, short, and has never been replicated. Later research looking at creatine and testosterone has not found a consistent rise in DHT, and a 2025 randomised trial that did measure hair follicles found no difference between creatine and placebo over 12 weeks.

Why Some People Still Notice Shedding

If you started creatine and then noticed more hair in the drain, a few other explanations are more likely:

Timing. Pattern hair loss often becomes noticeable in the late teens and twenties, the same age many people start lifting and supplementing.
Telogen effluvium. A sudden change in training, a cut in calories, poor sleep or stress can trigger shedding two to three months later.
Other supplements. Some pre-workouts and “test boosters” contain ingredients with genuine hormonal effects, unlike creatine.
Anabolic steroids or SARMs. These do raise DHT significantly and can accelerate hair loss in people who are prone to it.

If You’re Genetically Prone and Still Worried

If baldness runs in your family and you want to be cautious, you have reasonable options:

Take a standard dose (3 to 5 g a day) and skip the loading phase, which produces the biggest short-term jump in creatine levels.
Take monthly photos of your hairline and crown in the same lighting so you can judge changes objectively.
If you see real thinning, talk to a doctor about proven treatments. Stopping creatine alone won’t stop genetic hair loss.

Who Shouldn’t Take Creatine

Creatine is one of the most studied supplements, but it isn’t for everyone. Avoid it or ask a doctor first if you have kidney disease, are pregnant or breastfeeding, or take medicines that affect the kidneys. It can raise your creatinine level on blood tests, so tell your doctor you’re taking it.

Common Questions

Will stopping creatine make my hair grow back? If creatine wasn’t the cause, no. If your shedding was from a temporary trigger, it usually settles within a few months either way.

Is creatine HCl or monohydrate safer for hair? There’s no evidence either form affects hair. Monohydrate is the best-studied and cheapest.

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.
