¿Te quedas calvo si tomas creatina?

Hay un estudio en jugadores de rugby americano que relacionaba tomar creatina con el incremento de DHT (por tanto mayor caída de pelo), pero es un estudio muy sesgado y mal hecho; todos los más actuales indican que no hay problema en tomar creatina y pérdida de cabello, en la actualidad está totalmente desmentido.
Why the creatine-and-hair-loss myth persists
The hair-loss rumor stems from a single study conducted in 2009 in South Africa in which a group of college-aged rugby players took creatine every day for three weeks. The study showed a “statistically significant” increase in the participants’ levels of dihydrotestosterone (DHT), the testosterone byproduct that, in high concentrations, can shrink hair follicles, shorten the hair growth cycle, and cause hair to thin.
However, according to Dr. Antonio—who, along with an internationally renowned team of researchers, reviewed the most common creatine misconceptions for the Journal of the International Society of Sports Nutrition—none of the rugby players in the study actually experienced hair loss as a result of taking the supplement. What’s more, the people in the study who received the creatine started out with baseline DHT levels 23% lower than the placebo group, and their measured increase in DHT “remained well within normal clinical limits.” In other words, their DHT levels started out low and they stayed low. “‘Statistically significant’ is not the same thing as physiologically meaningful,” Dr. Antonio explains.
