Minoxidil works by dilating blood vessels in the scalp, which increases blood flow to hair follicles. This improved blood supply is believed to stimulate hair follicles, extend the hair growth cycle, and promote thicker and longer hair growth. While the exact mechanism is not fully understood, Minoxidil is thought to prolong the growth phase of hair (anagen) and delay the resting phase (telogen), which leads to increased hair density. It’s commonly used to treat hair loss conditions like androgenetic alopecia and is available as a topical solution or foam applied directly to the scalp.
