OK so about 6 months ago I dyes my hair almost black from blonde and now I want my hair to be blonde on top and black on bottom. I dyed my hair blonde but forgot to use a bleaching kit so I have blonde roots and dark brown hair. So I hae a couple questions
How long should I wait to bleach my hair?
Should I bleach all of it or just the part I want blonde?
After bleaching how long should I wait to dye it?
What products should I use to do the least damage to my hair?
