Does creatine cause hair loss? A 12-week randomized trial offers a clearer answer about creatine, DHT and hair follicles.

The creatine-and-hair-loss claim has circulated for years, largely because of concerns about DHT. But the latest direct evidence doesn't show that creatine causes hair loss.

Explains where the hair-loss concern came from Separates DHT from actual hair loss Reviews a direct 12-week randomized trial Helps men assess the claim realistically Where Did the Myth Start?

The concern largely came from research involving rugby players that reported changes in DHT, a hormone involved in male-pattern hair loss.

But measuring DHT isn't the same as measuring whether men actually lost hair.

That's an important distinction.

What Happened When Researchers Tested It Directly?

A 2025 randomized controlled trial gave resistance-trained men either 5 g/day of creatine monohydrate or placebo for 12 weeks.

Researchers measured testosterone, DHT and several indicators of hair-follicle health.

They found no significant differences between the creatine and placebo groups in DHT levels or hair-growth measures.

That's considerably more useful evidence than simply observing a hormone change.

Does That Prove Creatine Can Never Affect Hair?

No.

One 12-week trial cannot answer every possible long-term question, particularly for men with strong genetic susceptibility to male-pattern baldness.

But it does mean the popular claim that “creatine causes hair loss” is not supported by current direct evidence.

MEN35 Takeaway

Don't confuse a theoretical hormonal mechanism with demonstrated hair loss.

Bottom line: Current clinical evidence does not establish creatine as a cause of hair loss.
