How does minoxidil work for facial hair?

Minoxidil is a vasodilator that promotes increased blood flow to hair follicles, which can stimulate hair growth. When applied to the face, it may enhance the delivery of oxygen and nutrients to hair follicles, potentially encouraging the growth of facial hair in individuals who are genetically predisposed to develop it. While it is primarily used for scalp hair loss, some users have reported success in achieving fuller facial hair. However, results can vary, and it may take several months to see noticeable effects.
