Crafted by the experts in the L’Oréal Professionnel labs, Metal Detox is a quick and easy in-salon spray treatment, which can be continued at home with a shampoo and mask.

The crucial ingredient? A teeny-tiny molecule known as glicoamine.

“Glicoamine is a molecule that’s small enough to penetrate individual hair fibres,” explains L’Oréal colour specialist, Roz Orr.

“It targets and surrounds metal particles, using its chelating properties to bond with them and neutralise them, even when they’re sparsely distributed.”

Whether you’re getting a glaze, global tint, highlights or balayage, you can expect to see safer, more reliable results and a shiny finish, with the treatment taking a matter of moments, without adding any significant time on to your visit.

Then when it comes to maintaining your hair, you can also follow an at-home routine. First, wash your hair using L’Oréal Professionnel Metal Detox Shampoo, a luxurious foaming shampoo with a zingy citrus scent.

Then follow that up by applying the L’Oréal Professionnel Metal Detox Mask – leave it on for just 60 seconds to continue protecting your hair during washes.
