Creatine and Hair Loss: The Truth Uncovered
Reviewed by Dr Epameinondas Bonaros
Creatine, a popular supplement among athletes for enhancing performance, has often been linked to hair loss. This misconception primarily stems from an influential 2009 study on rugby players, which suggested a possible connection between creatine consumption and elevated levels of dihydrotestosterone (DHT), a hormone related to hair loss. However, a recent double-blind randomized study in 2025 provides more comprehensive insights, debunking previous claims.
The 2009 Rugby Study: Origin of the Misconception
In 2009, a study published in the *Clinical Journal of Sports Medicine* examined the effects of creatine monohydrate on the DHT-to-testosterone ratio among 20 male rugby players. The findings indicated a significant increase in DHT levels after creatine supplementation, sparking theories that creatine may accelerate hair loss due to increased DHT, which is known to contribute to male pattern baldness. However, this study did not directly assess hair loss, leading to speculative conclusions linking creatine to baldness.
The 2025 Double-Blind Randomized Study: Shedding New Light
Fast forward to 2025, a new double-blind, randomized, placebo-controlled study was conducted to directly evaluate the effects of creatine on hair follicle health. Spanning 12 weeks, the study involved 38 resistance-trained males, who were assigned either to a creatine monohydrate group or a placebo group. Contrary to the 2009 study, the 2025 research found no meaningful changes in DHT levels or any other androgenic effects that could negatively impact hair health.
- Study Methodology: Participants in the creatine group received 5g/day of creatine monohydrate. The researchers monitored androgen levels and assessed hair follicle health using advanced imaging technology.
- Findings: The results showed no significant differences between the creatine and placebo groups concerning hair growth parameters, DHT levels, or the DHT-to-testosterone ratio. All hormonal changes remained within normal physiological limits.
Conclusion: Creatine and Hair Loss - A Myth?
The 2025 study provides strong evidence against the notion that creatine causes hair loss. While creatine can increase DHT, these levels remain within normal ranges and are unlikely to trigger hair loss beyond what is genetically predisposed.
