is this a joke ? come on man are u here to piss us off? lol
Even those who bald early don't bald at 15...there may be exceptions but I think you are safe for a little while longer, or maybe never going to thin.
I have since age 17 been very paranoid about losing my hair, i am 27 today. So it's been rough 10 years haha.
I've seen a few 15 year old's here who had gone beyond NW2 and there was a guy back when I was in school who was around 15 who lost his forelock so it does happen. Can happen anytime after puberty hits. Anyway, I didn't see any pics here so nothing to comment on
