TyananW and Big B: your comments are vague, please explain your statements that minoxidil will NOT stop the balding process but will cause extra hair growth. How do you stipulate the vocabulary in the latter statement? By "extra hair growth" do you mean hairs that are not balding will be pushed to grow more actively? Thus, more hair in anagen on scalp at once? But if you mean extra hair growth related to balding follicels, then your comments, at this level, would be incorrect.
Moreover, I disagree at first glance about your statements. If minoxidil is famous for REGROWTH, then how is that not stopping, and, actually, reversing male pattern baldness? Further, once one stops minoxidil, the hairs that one maintained with it should be lost and in fact, many on the boards and even in clinical studies go through a shed period after cessation of treatment. The implication is that the hairs being lost would have succomb to male pattern baldness long ago if it weren't for the minoxidil. Strong evidence for this effect of minoxidil is due to the fact that minoxidil can actually regrow hair and maintain that hair for a relatively long period of time.
Maybe I am wrong, but that is my take.
