Ok, I'm probably miles off here, but I always thought:
Minoxidil = Regrowth
Propecia = Maintainence
So, how come hairs produced through minoxidil fall out if you stop minoxidil, but carry on with Propecia. Surely a DHT inhibitor would stop these hair-follicules from being clogged-up again.
Or are hairs produced by minoxidil 'not proper hairs' for some reason..??
