Suitable for natural or dyed hair, highlights, balayage and ombre, our professional-quality formula with effective colour pigments reduces brassy and yellow tones refreshing your colour without damaging hair. The colour pigments adhere to the surface of the hair instead of giving a chemical reaction in the core.

This hair mask, made with no ammonia or peroxide, is suitable for daily use and meant to be used on the same hair tone to enhance it. The effect remains visible for 2 to 3 washes.
