Product Features: #Hairbesties, when lifting the natural level 2-3 levels lighter, the double Ash Series gives you the most control for the coolest result possible!

#Hairbestie Tip: On a virgin application, mix desired color with 20vol on the rootagé re-growth. For the mids to ends, mix desired color with 30vol to achieve even lift & deposit; and, avoid "hot roots!". Process for the full time on dry hair.

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.
