L'Oréal Professionnel Paris Metal DX Shampoo has been developed for all hair types to prevent hair damage before it occurs. Hair wash for hair washing metals such as copper contained in our tap water penetrate the hair and increase the risk of hair breakage. Enriched with glicoamine, the only molecule small enough to neutralise metal particles in the hair fibre, Metal DX prevents hair breakage. The ultra-nourishing shampoo gently removes metal particles and provides instant suppleness and shine with its creamy texture. Pro tip: For optimal results, use the popular Metal DX mask after shampoo.
