Dying dark brown hair to jet black?

maybe try a temporary dye for starters to see if u like it. if u decide u want it permanent, it will be hard to change ur colour unless u grow the black out. u can get the home ones from the supermarkets or go to a professional. all permanent and semis have some form of peroxide in them so the colour can the hair. no u dont have to bleach ur hair though. hope this helped =) xoxoxo alisha
