COLLECTION: Serie Expert / Wash after wash, the metal in the Water penetrates your hair. It can attack the entire fibre and cause the colour to fade. In high concentrations, it creates a risk of breakage and unwanted highlights can appear. The anti-metal cleansing cream gently cleanses the fibre and eliminates the build-up of metal particles, such as copper and other particles of pollution. The result of a patented innovation, this shampoo is part of the Serie Expert Metal Detox range from L'Oréal Professionnel, which combats hair breakage and preserves hair colour. Sulphate-free*, its rich, creamy texture transforms into a rich lather. Hair looks healthier and regains its shine. HOW TO USE IT Apply to wet hair. Emulsify until smooth. Rinse off. For best results, follow with the Anti-Deposit Protective Masks.
