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 pre-colour treatment creates the perfect clean canvas for optimal colour results, by neutralizing metal inside the hair before any colour service. Colour results are true to tone, bright, and there is up to 87% less breakage**.
