Elevate color services with the next generation of demi-permanent toning. Colour + Gloss 6/5 6R delivers a vibrant, expressive red reflex to dark blonde bases without structural compromise. Operating on a pH-neutral mechanism, this gel completely replaces aggressive alkalis like ammonia and monoethanolamine (MEA) with Arginine, a natural amino acid that gently opens the hair structure. Infused with a premium oil trio of Argan, Macadamia, and Sunflower, it locks in oxidative pigments while acting as a care booster, creating a radiantly reflective, silky-soft finish.
