I bleached my hair from black to blonde its gone white at the roots and a dull yellow/orange colour I can't go to a hair salon so what would you recommend? Please help! :D

You should use a toner, it helps take out the brassy look, then in a few weeks bleach again to lighten.

Work the bleach up from your tips to your roots... bleach is activated by heat. Or else tone the roots to match the bottom.
