I recently went from a level 1 jet black (which covered turquoise and lavender direct dye) to a level 7-8 copper gold auburn in two sessions. I prepared my hair with Malibu C CPR and left it on for 30 minutes under heat. That removed the black two levels and the green/purple tones were showing. I then used Malibu C Color Correction which removed most of the direct dye. The next day I used Malibu C Color Prepare and then mixed a shampoo cap with lightener/40 volume and Malibu C Un-Do-Goo Shampoo which lightened it up enough to color it to a level 7-8 bright copper auburn! I only kept the shampoo on 25-30 minutes! I LOVE Malibu C products!
