Clear the copper for captivating colour.

L'Oréal Professional Serie Expert Metal Detox Pre-Treatment is part of 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 Pre-Treatment is designed to be sprayed onto hair before colouring or lightening. Its patented technology uses a molecule called Glicoamine to penetrate 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.

It's a leave-in, liquid texture spray and can be used with all colour and lightening brands. Application is simple and won't add any time to your colour service: simply spray on and leave to air dry while you mix your colour.

L'Oréal Professional Serie Expert Metal Detox Pre-Treatment comes in a 500-ml spray bottle.
