Does Creatine Cause Hair Loss? The Gym Myth Explained

If you're into fitness, you've probably heard the warning: creatine causes hair loss. This claim has circulated in gyms and online forums for years, causing many men to avoid one of the most well-researched and effective supplements available. But what does the science actually say?

The Origin of the Myth

The creatine-hair loss connection traces back to a single 2009 study on rugby players in South Africa. After 3 weeks of creatine supplementation, participants showed a 56% increase in DHT (dihydrotestosterone) levels. Since DHT is linked to pattern hair loss, the conclusion seemed logical: creatine raises DHT, DHT causes hair loss, therefore creatine causes hair loss.

Why the Conclusion Is Flawed

• Single study: No other research has replicated these findings
• Short duration: 3 weeks tells us nothing about long-term effects
• DHT remained in normal range: The increase was relative, not absolute
• No hair loss measured: The study didn't actually measure hair outcomes
• Correlation isn't causation: Even if DHT rose, that doesn't prove hair loss followed

What We Actually Know About Creatine

Creatine monohydrate is one of the most studied supplements in existence. Hundreds of studies have examined its safety profile, and hair loss has not emerged as a documented side effect. Major sports medicine and nutrition organizations consider it safe for healthy adults.

The Practical Answer

If you're genetically predisposed to androgenetic alopecia, you're going to experience hair loss whether you take creatine or not—it's driven by your follicle sensitivity to DHT, not your supplement stack. Focus your attention on evidence-based treatments (minoxidil, finasteride) rather than avoiding well-researched supplements based on forum speculation.
