For hair that is colour treated and wanting to maximise colour retention. Patented pH 4.5 Balancer Technology not only seals the surface of coloured hair like conventional colour care does, but most importantly, it freezes the colour pigments deep inside the hair matrix for ultimate colour perfection. Gently yet effectively cleanses coloured hair. Keeps colour pigments frozen deep inside the hair. Tightens and stabilises the hair matrix. Helps to optimise the pH level to 4.5. Protects hair structure both inside and out. Sulfate-Free technology uses mild tensides to bring the hair to its optimal pH 4.5 and actively prevent colour fade. Colour appears as vibrant as on day one until the next salon visit. To use: Apply to wet hair and massage. Rinse thoroughly.
