I Want A New Hairstyle...

I want a new hairstyle but there is one problem, just one small problem. My parents won't let me, specially my dad. I really wants to make my hair like those girls in 80's bands, or get wavy bangs. And then gt some hot pink highlights. I'm bored with this normal hairstyle >=O

My hair is like above, but I don't have that thick hair... and I don't have the bangs and I want them.... Oh, and my hair colour is natural black... I WANT TO CHANGE MY HAIRSTYLE!!! GRRR!!!
