There is some evidence suggesting that creatine supplementation might affect hair loss by influencing hormone levels. A study found that creatine supplementation led to an increase in dihydrotestosterone (DHT) levels by 56% after a 7-day loading period and these levels remained 40% above baseline after 14 days of maintenance¹. DHT is a more potent androgen known to be a contributing factor to androgenic alopecia, which is a common cause of hair loss¹².

However, it's important to note that the long-term effects and safety of changes in circulating androgens due to creatine supplementation are not fully understood, and further research is needed to draw definitive conclusions¹. If you're concerned about hair loss, it's advisable to consult a healthcare professional before starting creatine or any new supplement.
