this what has happened so far well I have previously dyed my hair black for a while now.. recently I just let my natural hair grow out, because it would some what match my original natural hair color. So one day I decided that I was tired of black hair so I wanted to experiment on bleaching my hair.. not realizing when I bleach it, that my natural hair was growing out I bleach it and my results came out uneven, the top came out nice and yellow and the bottom half came out like a strawberry reddish blonde.. so I freak out and went "back to black".. so now I done quite a few research on how to properly dye from black to blonde.. and I found a product that will completely remove all the black hair dye from my hair... but not the bleach.. so I want to know what can I do after the black is done and I still have uneven hair tones... but the thing is I want to know what would happen if I attempt to do this what would go wrong?. before I actually try to see this through.. I would really appreciate any advise given to me! Thank you :)
