Mechanism and action
Propecia: DHT, produced from testosterone by 5-alpha-reductase, drives miniaturisation of scalp hair follicles in genetically susceptible men, gradually shortening anagen growth phases until follicles produce only fine vellus hair… Rogaine: Minoxidil is a potassium channel opener that produces local arteriolar vasodilation.
