Product Features: #Hairbesties, the RR Series gives the purist form of ruby tones. I love mixing it with the CRC Series to create different variations of fiery tones! You can also mix with the BB or NI Series' to create more natural, chocolate cherry colors.

#Hairbestie Tip: Include 1/4 NI into your RR rootagé formulation & mix with 10-20V. For the mid-lengths to ends, mix RR with 30V. This helps avoid hot roots, creating believable results when lifting darker hair levels.

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.
