Kérastase Reflection Sulphate Free Shampoo For Colour-Treated Hair The zinc gluconate in this top-rated Kérastase Reflection Sulphate Free Shampoo For Colour-Treated Hair ($31) traps colour pigments to preserve and protect hair after a dyeing process. That process often leaves hair weaker (even if no bleach was involved), so the Kérastase Reflection Conditioner For Colour-Treated Hair ($34) and Kérastase Reflection Mask For Colour-Treated Hair ($56) offer extra care for any especially brittle ends.
