Hi guys, I am posting again since I have booked a consultation with another stylist in town, with great work and refferels. I ve been a hi lift blonde for 4 years, yet she clearly sugested that the only way to get rid of the dull warm tones would be bleaching, prob. with a low/20 vol developer. Of course I kind of freaked out, since my hair has already been through years of high ammonia dye, and now bleaching over it as well? (tho my hair is in a good shape, except for mildly split ends). another option would be to only do highlights w. bleach. In your experience, would bleach over hi lift be super damaging? How about the option of highlights only? Thank you so much in advance!
