Kérastase Masque Chroma Reflect is a rich radiance enhancing treatment masque for medium to thick, sensitised coloured hair. Its enriching formula will transform the hair's texture leaving it silky soft & hair colour brilliant & luminous. During the colour process hair cuticles can become sensitised & raised, affecting the final results so that rays of light hitting the hair are diffused unevenly, spoiling the reflection & leaving hair appearing lack lustre. Kérastase Masque Chroma Reflect is formulated with cationic polymers, ceramide, candelilla wax & a fibrionic system to remove the dulling residues on your hair & leave it silky smooth & with mirror-like shine.
