Protect your colour or balayage with L’Oréal Professionnel’s Serie Expert Metal Detox Anti-Deposit Protector Mask. With every wash, copper deposits can accumulate in the hair fibre, causing dullness, discolouration and even breakage. The innovative hair mask helps to protect the hair against copper-induced fading, working to maintain vibrancy, while leaving the locks feeling smoother and softer. The creamy mask is enriched with an uplifting citrus and woody fragrance to create a luxurious, salon-like experience at home. Formulated to compliment the metal detox pre-treatment and shampoo, the mask is the perfect final step for your routine.
