Can creatine cause hair loss?

Creatine is not proven to directly cause hair loss in most people. The concern mainly comes from discussion around hormones and one small study that looked at DHT changes, not from strong evidence that creatine itself makes people bald. Hair shedding can come from genetics, stress, thyroid issues, iron deficiency, illness, crash dieting, new medicines, or scalp problems. If hair loss is sudden, patchy, or heavy, it is better to investigate those causes instead of blaming one supplement automatically.Mmayoclinic.orgMmayoclinic.org
