For hair that is colour treated & wanting to maximise colour retention. Patented p H 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 & stabilises the hair matrix. Helps to optimise the p H level to 4.5. Protects hair structure both inside & out. Sulfate-Free technology uses mild tensides to bring the hair to its optimal p H 4.5 & actively prevent colour fade. Colour appears as vibrant as on day one until the next salon visit. To use: Apply to wet hair & massage. Rinse thoroughly.
