Powered by Anti-Porosity* Technology, the L'Oréal Professionnel Serie Expert Metal Detox Pre-Shampoo Treatment is designed to neutralise excess copper in the hair to protect it from damage.

The lightweight gel helps to prevent excess absorption of water with metal using a 2% concentration of Glicofiller. The hydrating treatment simultaneously works to provide up to 72 hours of nourishment, smoothness and softness**, while detangling the strands for enhanced manageability.

In just one use there is up to 96% less breakage***, promoting a stronger look and feel. Suitable for all hair types and textures, the colour-safe treatment perfectly prepares strands for your shampoo. Complete with an addictive citrus musk fragrance.
