hey man i am 16 aswell and like you i started to recede at 15. I just started Fincar(1/4) 3 days ago and i think you should start it aswell. I mean lets be honest, unless you are the cool kid of your school then your not going to be able to handle hairloss very well at 16. We are both destined to have horse shoes unless we take action rather than sitting around with the "Maybe it wont get any worse" mentality when we know there is a big chance it will. This is my look on it but i think that if i was norwood 4/5 before the age of 20 then it would some what damage me socially, so in my eyes the 2% risk of sides is only a blip on my radar compared to hairloss so young]
