Cheers, I visitied a derm last year who more or less told me he couldnt see any signs of male pattern baldness and at 30 I was getting a mature hairline, should I be worried about nw2 at 30? So what is a mature hairline surely it involves some recession? I have a full crown and my hair grows back from being shaved very thick, its really in the process of growing back. Still start finasteride as a possible prevention?
