i need help. eminem's hair?

Yo, sup y'all. Im 14 and a big hip hop fan.I wanna dye my hair but my mum doesn't let me. I love Eminem so i want to dye my hair like his colour. How can i convince my mum though. Any Ideas.

P.S. Also do u think this is a good idea? And im also open to dye parts of my hair and not the whole thing. And i guess i mean bleach wen i say dye cos thats wat em does.

P.S. (again)- any other ideas apart from this? My hair is now short and medium brown. It aint to thick but doesnt spike too good.
