Longevity & AgingCreatine Does Not Cause Hair Loss, First Controlled Trial Confirms
A 12-week double-blind randomized controlled trial involving 38 resistance-trained males found that daily creatine monohydrate supplementation (5 g/day) did not increase dihydrotestosterone (DHT), alter the DHT-to-testosterone ratio, or negatively affect hair follicle health compared to placebo. Hair density, follicular unit count, and cumulative hair thickness were assessed using the FotoFinder dermoscopy system and trichogram testing at the vertex scalp region. While total testosterone rose and free testosterone declined over time in both groups, these changes were independent of supplementation. The study is the first to directly measure hair follicle outcomes following creatine use, providing robust evidence against the widely circulated claim that creatine accelerates hair loss.
