When washing hair with water, a build-up of metal particles occurs inside the hair fibre which negatively impacts colour results and enhances the risk of hair breakage. L’Oréal Professionnel introduces a ground-breaking solution to this problem with the Metal Detox Hair Protocol, a member of the Serie Expert collection of targeted hair care products developed to meet specific hair concerns. Using Metal Detox as part of your hair regime will improve colour vitality while reducing hair breakage. Hair is less porous, intensely nourished, stronger, and left with incredible shine. L’Oréal Professionnel Metal Detox Mask is the last step of the Metal Detox hair protocol in-salon and at-home. This rich and creamy hair mask for coloured hair prevents new metal particles from coming back into the hair to prevent further breakage and loss of colour. This detoxifying hair mask can be used at-home after applying the Metal Detox Cleansing Cream Shampoo and Anti Deposit Protector Care Conditioner. When used in combination, the Metal Detox shampoo will detoxify hair from metals, while the Metal Detox Conditioner and Hair Mask will prevent new metal particles from returning. The result? Incredibly soft and shiny hair.
