HAIR TYPE: Damaged Hair / COLLECTION: Serie Expert / Protect your colour or balayage with the L'Oréal Professionnel Serie Anti-Copper Deposition Protective Mask. With every wash, copper deposits can build up on the hair fibre, causing dulling, discolouration and even breakage. The innovative hair mask helps protect hair against copper-induced fading, working to maintain vibrancy while leaving strands smoother and softer. The creamy mask is enriched with a citrus and woody fragrance to create a luxurious salon experience at home. Formulated to complement the pre-treatment and metal detox shampoo, the mask is the perfect final step to your routine.
