Ashley pink hair..

Hello,
My name is Ashley Wallace, and I'm a student at Northgate High School. I have a problem, and the problem is, that my hair color isn't acceptable at my school. On the school group photo, my hair color has been changed into a mousy brown instead of my normal pink hair. Even my head teacher Neil Watts has said, that my hair color doesn't show a good example of the school's policy. I think it's humiliating and rude, so I told my friends about it, and they agree. I know the hair color isn't normal, but I think it gives a good image of my personality. I really like the color, and I will never change it. My family supports me, and if i have to move to another school because of my hair, I'll do it.
