I dyed my hair dark blue last year and got in trouble.
i tried explaining to them that no one would want to dye their hair strange colors but me (because my school only has about 400 students and their all mostly preps).
i have naturally black hair so how can i dye it to look more punk?
it would have to be a natural color (like blonde, brown, natural red)
please give suggestions that can be done at home.

THANK YOU!!
Update: i have olive-ish skin so i'm not sure if bleach blonde would look good.. it's not too dark though
or blonde at all.
any opinions about sorta-dark skin and blonde hair?
permanent colors please
