tried rogaine... was way too expensive and didn't work for me (receding hairline).
now I just say 'ah well' and move on. Every man on my dad's side of the family is bald - it's pretty much unavoidable for me. Get some cool hats (I like those mesh net-type cotton caps personally! they're stylin'!), buzz the hair short if you have to, and realize that it's not really that important in the grand scheme of things.
my girlfriend still loves me! people still like to be my friend! I'm not a horrible balding freak! so many people are bald in north america - we can't all be models
just don't go to australia - a friend of mine from there was here in canada for a year....she couldn't believe how many men are bald/balding!!! apparently it's not nearly as common there.
