semi-long hair

I'm semi-long hair. It's very hot in summar but it's very usual in winter because it's protect from cold. It plays a role like a hat. It's covered both my ears and nape.However, I must cut it because I must do job hunting soon. I must also change a hair color from brown to jet black. Finishing job hunting, I thought I will dye my hair. And only one time, I want to dye it pink like hide.
