Metal DX Shampoo by L'Oréal Professionnel Paris is designed for all hair types to prevent hair damage before it happens. Shampoo after shampoo, metals* such as *copper, which is present in water, penetrate the hair and cause the risk of hair breakage and colour changes. Enriched with glicoamine, the only molecule small enough to neutralise metal particles in the hair fibre, Metal DX prevents hair breakage and colour changes. The ultra-nourishing shampoo gently removes metal particles and provides instant softness and shine with a creamy texture.
