Thanks for your replies guys!
Yeah, I'll probably upload a pic soon. My dad and grandad on my mums side were both very bald! so i'm prepared for mine to be the same, especially as it has started so young. There is no miniturisation in any other areas yet, its only at the front. Maybe the propecia has been effective in preventing hairloss in the crown?
I actually use Fincar which is a generic version of Proscar and is a hell of lot cheaper!. I know some people who use it and they have actually had some regrowth, so i don't doubt it's effectiveness .
I understand what you are saying about not having enough donor hair to fill in balding spots, but to me it is more important to have hair at the front. It frame's the face and is generally the part of the hair most people look at. You say it would look unnatural, is this because the frontal transplant hair would look too thin without hair on the top of the head to kind of support it?
