Hormonal imbalances, particularly involving estrogen and androgens, play a significant role in hair health. Estrogen, often considered a "hair-friendly" hormone, helps keep hair in the growth phase longer. On the other hand, androgens, such as testosterone, can shorten the hair growth cycle and cause hair follicles to shrink, leading to androgenic alopecia. Conditions like PCOS often result in elevated androgens, contributing to hair thinning.
