Copper-bottomed protection for your colour.

L'Oréal Professional Serie Expert Metal Detox Mask is third line of defence in L'Oréal’s innovative range that's designed to neutralise excess copper in your clients' hair. L'Oréal research shows up to 64% of people in the UK have excess copper in their hair, and that excess copper can make hair colour less true and leave coloured hair more prone to breakage.

The Metal Detox Mask is designed to be used after colouring to prevent copper being redeposited in the hair fibre. It should be used in conjunction with Metal Detox Pre-Treatment and Metal Detox Shampoo.

The patented technology in Metal Detox is a molecule called Glicoamine which penetrates the hair fibre, trapping and neutralising metal to ensure that colour is true and fully developed. In tests, hair was also 87% less prone to breakage.

L'Oréal Professional Serie Expert Metal Detox Mask comes in a retail size of 250 ml or a salon-sized 500 ml.
