The Amika Colour pHerfection Shampoo is sulfate free, Ph balanced and contains UV filters to prevent colour fading.
The amika Obliphica Colour pHerfection Shampoo is specifically formulated for colour treated hair. This sulfate free formulation counteracts the effects of hard water, binding the minerals (calcium, magnesium, iron) from depositing onto the hair and dulling colour. UV filters and antioxidants also protect colour while the pH range of 4.55.5 closes the cuticle and locks in colour. Hair is left shiny, radiant and the colour preserved.
