Hello Cindy,
There are no permanent colour brands on the market that are recommended on the day of a relaxer. We recommend that you colour your hair 2 weeks after the relaxer day. This allows the hair time to recover from the relaxer and does not put so much stress on the hair in the long term. The brand that I would recommend for ethnic hair is Dark and Lovely Color Intensity which is available in 6 gorgeous colors. For caucasian hair I would recommend L’Oreal Excellence Creme which is available in 19 delectable shades.
KInd regards
Heidi
