I'm 34, had my first HT at 32..I understand your view, but the thing is, when I had my first HT, my crown was not thin or thinning, it was BALD. Dead, shiny, smooth BALD. The crown was done and starting to move forward, other than some shed a few months after my 2nd HT, I haven't lost ant more hair. Propecia would have made no difference at all. The problem with another 2000 grafts in my crown (other than the extra $6-7k) would be that I'd have over 5000 grafts in my crown alone..doesn't leave much for the rest of my head, should I need it down the road.
