No, creatine won’t cause hair loss.

The excerpt discusses recent research regarding the long-standing rumor that creatine supplementation causes hair loss.

Key Points:

1. Background:

   • Creatine is a popular supplement among athletes and gym-goers.
   • A rumor linking creatine to hair loss, stemming from a 2009 study, has persisted for over 15 years.

2. Initial Study:

   • The 2009 study followed rugby players and noted a potential increase in the conversion of testosterone to dihydrotestosterone (DHT), which is associated with androgenetic baldness.
   • The study did not measure hair loss, and no players reported experiencing it.

3. Recent Research:

   • A 2025 randomized controlled trial aimed to test the claim directly.
   • Researchers studied 45 resistance-trained men assigned either creatine or a placebo.
   • Results showed no significant differences in DHT levels or hair growth metrics between the two groups.

4. Expert Opinions:

   • The study was considered pioneering in assessing hair health in relation to creatine use, providing strong evidence against the hair loss claim.
   • Experts emphasize the importance of consulting a healthcare professional if concerned about testosterone or hair loss.

5. Advice for Creatine Users:

   • Initial water retention is normal.
   • Stick with creatine monohydrate.
   • Combine creatine with exercise for optimal benefits.

The overall conclusion is that creatine is a well-studied, safe supplement that likely does not cause hair loss.
