6 months ago I died my hair black and then me and a friend bleached my hair out to get rid of it when we bleached it the roots came out lighter than the rest of my hair I am naturally a blonde and then I died it another color and I kept on dying it how would I be able to get all those different hair dyes out of my hair and try to go back blonde

In order to go blonde, you will need to lighten your hair with bleach and then apply a toner. If you want a decent blonde color, visit a salon and get your hair professional done.
