I have black and blue hair ;D good choice
well you already seemed to have rebelled against them once, why not twice?
You have three options;
1. Dye your hair by yourself
2. Somehow convince your parents to let you do it
3. Just leave it as it is. (or maybe color it full black with no blue?)
Trust me, you’ll be so happy when you change it, its so much fun to color your hair, no parent likes it but its just hair, its not serious. I mean do they want you too wait until you’re 18??that’s not very smart since your gonna wanna look for a job by then..
and hey, whats the worst they’ll do? we live in a 1:st world, all the can do is ground you, yell at you or take away your money.
Do you wanna regret not doing it, or regret doing it?
You see which choice I made, now its your turn :)
