Thanks a lot everyone 
You've given me a lot of confidence and I feel more secure about the way I look. My head shape may be different but It shouldn't matter, without it I wouldn't be me. It probably just looks worse to me than it does to other people. I'll definately be giving it a go.
Thanks once again everyone.
The bad thing about your situation is that you are in your high school years and the high school years are unique in that a person's peers are ruthlessly vicious in picking on others for anything even remotely different. For all the talk teens give for their love of individuality, they are the most homogenous age group of our species and they will not be kind if you decide to defy conformity and express individuality in a way that is not "cool".
It took me a while to figure out the Grand Unifying Theory behind all things "cool" and "uncool", and the following really is the result:
Something is "cool" if it directly involves getting laid or involves the pursuit of getting laid, and everything else is "uncool". Unfortunately, when teenagers are involved, someone doing something "uncool" requires them to pick on that person non-stop.[/i]
Therefore if you shave your head it will be considered "cool" if you are doing it for the pursuit of getting laid, but if you are doing it for your own reasons (and it looks like you are) then it will be seen as "uncool" and vulnerable to the repercussions. The fact that you seem uncertain about the look may make them especially vicious if they can smell vulnerability on you.
Fortunately, while the rules on cool and uncool remain the same forever, people older than
high-school-years-old usually don't feel compelled to bully those who break conformity. It really is funny how drastically this childish attitude drops even between a senior year in highschool and a freshman year in college. Generally outside of high school the insults come from friends who are picking on you out of respect, and others tend to keep their mouths shut.
I hope that didn't discourage you too much, but I just wanted to warn you of the bulls**t you may encounter because teenagers are, in general, ... I guess I shouldn't go there. Anyway, the good news is that you are only a couple years off from being free from it.
