SOURCE-LINKED STUDY SUMMARY

Does creatine cause hair loss? A 12-week randomized controlled trial.

Journal of the International Society of Sports Nutrition ·

Human

Full paper summarizedQuality not appraised
What was studied
Double-blind randomized trial tested whether creatine changes DHT, testosterone or directly measured scalp-hair health.
Who / model studied
Resistance-trained men aged 18–40; 45 recruited, 38 completed, with one missing the final hair assessment.
Studied dose & schedule
Oral creatine monohydrate 5 g daily versus maltodextrin placebo 5 g daily for 12 weeks; participants maintained habitual diet and training.
What the study found
No treatment-by-time effects for DHT, testosterone, hair count, density or thickness. Total testosterone rose 124 ng/dL with creatine versus 216 with placebo, without a significant treatment effect. No side effects were reported in either group.
Limitations & context
Small male-only sample and 12-week follow-up cannot rule out longer-term effects. Family history of hair loss was not recorded; scalp androgen concentrations were not measured.
