Product Features: #Hairbestie, create the blue-black color you dream of! The MB Series can also be intermixed with any of the Silver Smoke or Dusty Lavender shades for endless color combinations. I can't wait to see what you create!

Instructions for Use: #Hairbestie, mix one part Permanent Color Crème with one part Permanent Developer 10-40V (1:1), and apply color. Process for 30 minutes. I recommend up to 40 minutes for gray coverage.
