Melatonin’s Effect on Skin and Hair

[16][17]

Melatonin also affects hair growth, as the hair growth cycle in mammals is under circadian control. [28]  In an open-label, uncontrolled study of topical melatonin involving 1891 male and female patients with androgenic alopecia, at 3 months 61% of patients had no hair loss, compared to 12.2% at the start; 22% had new hair growth at 3 months compared to 4% at baseline.
