Might as well focus on other things and get on with my life.
DING DING DING...you've found the correct answer.
What I don't get is that you're a good looking guy with the shaved head and you apparently have a beautiful girlfriend/wife already, so what's the concern with hair? I think by shaving for awhile and maturing a bit you'll realize that there are much more important things in life than worrying about getting your hair back.
^speaking of beautiful wives (no disrespect meant Mr T. but you are one lucky man)
...Oh, hey, while you're at the Doctor's office getting the prescription for Propecia, might just as well drop by your Urologist to make an appointment for your emasculation. Of course, that's just for aesthetical purposes, your testes will already be dead so why carry around a useless piece of flesh?
In short, DON"T DO IT.
