Thanks for the replies guys.
I am 19 and I think I'll be pretty dam bald by the time im twenty five. My girlfriend says me losing my hair is not a bad thing, however me worrying about it so much is.
I personally believe the only reason we have this perception of bald people is because of the way bald people act ashamed of their appearances. If you can be comfortable with your looks other peple will be comfortable with your looks too.
I'm still gonna give propecia a bash P
Keep the opinions coming guys.
