Is there a link between creatine and hair loss?
Creatine has been linked with hair loss since 2009, when the results of a small-scale research study were published. Researchers found that creatine use in a small group of college-age rugby players increased DHT [4]. DHT — or dihydrotestosterone — is the sex hormone responsible for male pattern hair loss.
The study found a DHT increase of 56% following the first week of a creatine supplement regimen where the rugby players were creatine-loading. For the following 2 weeks after when the athletes tapered down their creatine intake to maintenance levels, the DHT amount in the rugby players’ blood remained 40% above baseline.
However, researchers stopped observing the rugby players after these three weeks. As a result, they were not able to determine in this short period of time if hair loss occurred nor were they assessing for hair loss in the rugby players.
It’s unlikely that noticeable hair loss would have occurred during this short period. So it’s impossible to determine if these raised DHT levels actually contributed to hair loss in this instance. The researchers were only interested in measuring the DHT to testosterone ratio after creatine consumption.
Furthermore, it should be noted that the rugby players’ DHT levels were 23% lower than those in the placebo group to which they were compared. Even when the DHT levels increased in the rugby players, the DHT levels remained at normal levels. Further studies regarding creatine supplementation have taken place since the 2009 South African study and have found no evidence to support the link between creatine use and hair loss due to increased DHT levels [7].
Despite the methodology of the study and evidence linking creatine to hair loss being tenuous at best, the study helped to fuel speculation and rumours that creatine was responsible for hair loss. Most evidence connecting creatine supplementation to hair loss is largely anecdotal. This may be due to the link between anabolic steroids and hair loss (steroids such as Anavar may be linked with hair shedding).
