Well I had my hair colored brown red and blonde about 10 mo ago because I had gotten pregnant so I let it grow out a little and now the blonde was really dry and I wanted to cover it up so I colored it dark brown and the blond came right through it so then I did it black and again the blonde came through that to and now I'm going to be getting married and I want to make all this color go away can I? And how? The black has faded sooo much that you can see the blond and the brown I really need

There is a process called a tint back, where a stylist actually tries to match your natural hair color... check this website out (last paragraph) and it explains it more detailed.
