L\'Oréal Professionnel Serioxyl is an intense thickening range that immediately helps hair look denser and lifted. It helps improve the look of the hair fibre density and is ideal for use on fine, noticeably thinning, coloured hair. The Clarifying Shampoo cleanses and removes residue from the scalp and hair. As part of the L\'Oreal Professionnel Serioxyl programme, this densifying shampoo for coloured hair helps towards creating visibly thicker and fuller looking hair in an instant.
