I have really long black hair. I've been dying it black - level 1 for 3 years . Now I'd like to remove the black in order to achieve a deep brown color. My hairdresser told me , she had a hair color remover that stripps out all the black equally along the hair, wit no significant damaging. But I'm a bit afraid of how ''significant'' would that damage be because my hair is in excellent condition. It's really long, healthy and shiny. Everyone around me adores it, so do I but I really want to put this black off, cause I think it adds years on my face. So what am I supposed to do ?
