Backed by 7 years of research and 7 patents*, L’Oréal scientists worked hand in hand with hairdressers around the world to create Metal Detox. Research found that copper metals absorbed into the hair can cause a higher risk of breakage and unpredictable colour results during the colouring service.

Metal Detox is a haircare innovation powered by Glicoamine. The patented technology helps to neutralize (de-activate) these excess copper metals in the hair, helping to prevent them from interfering with the colouring process.

This award-winning mask is the final step in the Metal Detox regimen which should be used after the Metal Detox Pre-Treatment Spray and Shampoo for best results. This mask was awarded best conditioner for coloured hair in the Cosmopolitan Beauty Awards 2021.
