COLLECTION: Serie Expert / Professional shampoo for long-lasting colour, less breakage and more shine. This refill contains 73% less plastic than the classic 500ml bottle. L'Oréal Professionnel Paris Metal DX Shampoo is designed for all hair types to prevent hair damage before it happens. Wash after wash, metals such as copper, present in water, penetrate the hair and cause a risk of breakage and color alteration. Enriched with glycoamine, the only molecule small enough to neutralize metal particles in the hair fiber, Metal DX prevents hair breakage and color changes. This ultra-caring shampoo gently removes metal particles and its creamy texture provides immediate softness and shine. This refill contains 73% less plastic than the classic format.* * Compared to an original 500ml bottle.
