Does Creatine Cause Hair Loss?

No. Creatine does not cause hair loss. This is one of the most persistent myths in sports nutrition, and it traces back to a single 2009 study that measured something entirely different from what the myth claims.

Where the claim comes from

In 2009, a group of 20 college rugby players in South Africa participated in a study on creatine and hormones. The researchers found that participants who took creatine saw elevated levels of a hormone called dihydrotestosterone (DHT). That finding was picked up by fitness forums, stripped of its context, and turned into: creatine raises DHT, DHT causes hair loss, therefore creatine causes hair loss.

The problem is that none of those three steps is as straightforward as the shortcut implies.

What the 2009 study actually measured

Not a single participant in that study was assessed for hair loss. The researchers measured DHT as one of several hormones, found a transient increase, and that was the extent of the hair-related finding.

The protocol was also far outside normal supplementation: 25g per day for seven days, which is five times the standard daily dose. The DHT elevation returned to normal ranges within three weeks, even while participants continued supplementing at a maintenance dose. And the effect only appeared during the loading phase, not during normal use.

Does DHT actually cause hair loss?

DHT can accelerate hair thinning in people with a genetic predisposition to androgenetic alopecia, which is the most common form of pattern baldness. The key word is predisposition. DHT acts on follicles that are already genetically sensitive to it. If that sensitivity is not part of your genetics, elevated DHT does not produce meaningful hair loss.

Even for those who are genetically susceptible, the mechanism requires sustained elevated DHT levels over a long period, not a short-term fluctuation during a week-long loading protocol.

What the wider research shows

Every study published since 2009 that has examined DHT and creatine at standard doses has failed to replicate the original finding. A 2021 systematic review in the Journal of the International Society of Sports Nutrition looked at the full body of evidence and found no credible link between creatine supplementation at recommended doses and hair loss or hair thinning.

More than 1,000 peer-reviewed studies have now been conducted on creatine monohydrate. Hair loss has not appeared in adverse event reporting across any of them.

What about creatine gummies specifically?

The form of creatine does not change this picture. Whether you take creatine as a powder, capsule, or gummy, the molecule is the same: creatine monohydrate. The delivery format has no bearing on DHT or hair biology.

The bottom line

At 5g of creatine monohydrate per day, there is no credible evidence of any link to hair loss. The 2009 study used an aggressive loading protocol, measured DHT rather than hair, found a temporary increase that normalised quickly, and has never been replicated at standard doses.

If you are avoiding creatine because of this concern, the evidence does not support that caution.
