A little bit about androgens and the anagen phase of hair growth before we take you to the benefits of melatonin.
Hair growth in hair follicles occurs in three phases and anagen is the first phase. In healthy hair, most hair follicles are in the anagen or active hair growth phase. Hair grows about 1 cm every 28 days at that time.
Melatonin receptors are present in hair follicles. Through specific chemical reactions, melatonin is known to inhibit the action of androgens. This in turn, lengthens the anagen phase, increases hair production and prevents hair loss. Androgens are hormones that can reduce the anagen, or hair growth phase and cause baldness.
