i had a dark blondish hair color.. with light highlights..
i decided to change my color.. i wanted my hair all one color.. a lightish blonde, but i have a very low budget so i decided to do it myself and went to the store and bought a blonde hair color (Clairol - Born Blonde 'Original') .. it turned out terrible!!

my roots are like white and the rest of my hair is either orange or yellow. I need to fix it asap because i am going back to school in 4 days!! but like i said i am on a low budget.. how can i fix my hair and get it back to like a normal blonde color.. i heard about the volume 20 stuff but i have no idea what that means? if someone can help me thatd be great!!
