David my now deceased stylist used this for the unique hair colors. He used the Pravana brand color lifters as well. We used the Pravana color lifter as the non traditional hair color shows up on lighter or practically colorless hair. To optimize the color longevity/color payout I recommend sulfate free shampoo and conditioner once a week and become EXTREMELY friendly with dry shampoos. I used the Living Proof or Batiste dry shampoo when I had the Pravana Vivids in.
