I have a client who used to get a full head of highlights, but now has 4 inch of regrowth , natural level 6. But now wants change to go to a level 5 brown with copper lights. I know I can prepig hair with perfection, but then I would have to lift lights again to lift the /44 perfecton out and to put a copper on. Is there an easier way around this where I can get my copper done at the same time, maybe 8/43 colour touch to prepig with 1.9. I never do copper to be honest mainly highlights.
