This treatment provides hair with an instant colour boost and a nourishing treatment to refresh, tone and revive colour in just 3 minutes. Recommended for dull and dry light brown to medium brown hair wanting to eliminate warm tones, this colour boosting treatment uses Cationic Hair Dye to instantly refresh and tone colour-treated hair. This nourishing treatment revives hair by softening and conditioning, with a formulated blend of Cetrimonium Chloride and Panthenol to repair damaged strands. Added Benzophonene-4 protects the hair cuticle so colour is retained for up to 8 washes. This anti-static treatment restores and maintains moisture balance to reduce frizz and provide brilliant shine.
