Hey there. Firstly, I know how you feel - self conscious? Worried? Anxious?
I lost my hair relatively young, and knowing it is happening is hard to take. I was worried about what people (women) would think. Let me tell you that generally, THEY DON'T CARE.
You are at the age where people generally are still quite immature, so any childish comments you get you will have to ignore for now. You have to rise above it all - be a man, not a boy. Attract women, not girls..!
If you decide to 'do the deed' and shave it off, I can pretty much guarantee that a, it won't look as bad as you expect, and b, you will have a huge weight lifted off your shoulders. Is a scary thing to do though as theres no going back..! At first you will look strange - this is natural.
Have a read of this:

Yes, I have a 'skinhead', and my mates occasionally take the piss - especially if they haven't seen me since I cut it all off, but I can still get the women, I'm probably more confident and I feel more self assured.
I'd advise against all the pills, potions and lotions. The majority of these have side effects such as impotence and loss of sex drive - do you think a woman will want you then???
