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.
