This salon treatment is about to transform your hair-colouring routine - here’s everything you need to know

Whether you’re a salon regular or toying with the idea of a new shade, here’s why this extremely clever process should be on your radar…

Whether you’re looking for a total reinvention or a subtle shift in what you’re already working with, colouring your hair is one of the easiest and most effective ways to change up your look.

However, it’s always been a process with occasional drawbacks, from unsightly brassiness to varying degrees of hair damage.

That’s why Metal Detox from L’Oréal Professionnel is such a game-changer.

A pre-colour treatment designed to tackle the effects of damage caused by excess copper deposited within hair fibres, it’s about to transform the way your hair looks post-salon.

Here’s how it works, and why you need to incorporate it into your hair-colouring routine…

1. How does copper damage your hair?


How does copper wind up in your hair to begin with?

Put simply, many of the pipes that supply your shower head are not in the best state of repair, with steady erosion over time resulting in a surprising amount of metal ending up in the water.

Shockingly, UK tap water contains a 64% concentration of metal in certain areas, meaning copper can start to accumulate in your hair wash after wash.

As well as weighing down your hair, giving it a straw-like consistency, the presence of excess copper becomes even more of an issue when attempting a colour treatment.

As copper particles accumulate inside the hair fibre, they react with the oxidant in colour and bleach products, leading to unreliable colour results and an increased risk of breakage.

If you’ve ever seen a greeny, metallic sheen creeping into your hair, or your colour treatment has swiftly faded or become murky, excess copper could well be to blame.

Not only that, but copper particles actually accumulate inside the hair fibre as well as outside the hair fibre, making them tricky to tackle with a standard shampoo.

2. How can you treat it?


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.

3. What results can you expect to see?


First and foremost, by booking a Metal Detox treatment every time you visit the salon, you can colour your hair to your heart’s content, experimenting with hot pink highlights or an all-over bleach, with less fear of damage.

As well as offering 87% more protection against breakage*, the treatment also boosts shine and provides a “truer” shade when colouring your hair.

Then by using the at-home shampoo and mask, you can ensure your new shade lasts longer, without the fading or discolouration you might otherwise expect to see, while also reducing any further build-up ahead of your next treatment.

Colouring your hair will never be the same again.
