Hi, I have dyed my hair black for about two months but I am ready to go back to my natural brown color, I have not dyed it for over a month so my roots are getting very big and there is a lot of brown coming out in my hair. I can't wait to grow it out it takes to long, but I also don't want to damage my hair with bleach. I was told that if you put a little bit a baking soda in with your shampoo it would take out the black, but I have never used it before. Or one of the color zap formals by Loreal. Has anyone used these or recommend something? I am desperate! THANKS
