cut it shorter, bleach it, and become a Maniac Panic girl! Different highlights in crazy colors in cool tones and stuff, and you can change it every few months!
I was going to do that (my hair has a big blonde streak at the front and smaller highlights behind it) and I was going to get different shades of purple. Darkest on the bottom, lightest for my highlights, and the medium for the rest! (Didn't because I got a job that didn't allow it)
I couldn't cut my hair, though. (I have really long hair. and I have a phobia of cutting it) if you do cut it, you need less hair color.
but of course, thats pretty crazy. if your going more normail looking... knit yourself a wig! haha, uum. I'm not too good at the normal looking ones, ha.
