Hi! I’ve been colouring my hair at home for years with XP100 intense radiance 11.1 with a 12% 40 volume developer and got great results. I’ve always had a natural dark band at the nape of my back that I never colour as I liked the effect of the 2 tones, however the new hairdo went to yesterday has cut the back of my hair to far up and now I have a 2” dark band of virgin hair uncoloured which looks weird!
Do any of you hairdressers/colour professionals know if my XP 11.2 will lift my virgin hair light enough to blend with the rest of my blonde? Please help xx
