Topical MINOXIDIL works by PROLONGING ANAGEN (and shortening telogen, hastening the exit from it - which explains the transient shedding in the first weeks), and it also ENLARGES the miniaturised follicle, reversing miniaturisation so that vellus hairs become terminal. It acts as a potassium channel opener requiring sulphotransferase activation, must be continued indefinitely, and can cause hypertrichosis at distant sites from spread or systemic absorption, so growth is not confined to the scalp.
