Minoxidil is classified as a vasodilator, which means it works by widening blood vessels. When applied to the scalp, it increases blood flow to the hair follicles, potentially prolonging the growth phase of the hair cycle and reducing hair miniaturization. It’s crucial to note that minoxidil does not address the underlying cause of most hair loss—dihydrotestosterone (DHT), a hormone derivative that shrinks hair follicles in individuals with androgenetic alopecia. Because of this, minoxidil essentially serves as a “band-aid” solution, temporarily improving hair density and reducing hair fall without targeting the root cause.
