Im naturally a very fair, light brown colour hair and I died it black about 3 months ago but because my hair is so long I used two hair dyes to cover it. Unfortunately it didn't and the ends of my hair stayed the same light colour.

Now my roots are coming through so I have light roots and light ends of my hair and the rest is black, but with red because of the fading. I wondered if anybody knows how I can speed up this process. Because my hair is so long I don't want to leave it to just grow out it needs to fade.

Im currently using vosene shampoo and it doesn't seem to be working as of yet does anyone have any other ideas? Thanks a lot
