The L'Oréal Professionnel Serie Expert Metal Detox Pre-Shampoo Treatment (250ml) is a breakthrough professional formula designed to neutralise excess metals (like copper) inside the hair fibre before shampooing. Metals accumulate in hair due to water exposure and can cause breakage, dullness, and colour fading. With patented Glicoamine technology, this pre-shampoo treatment penetrates deep into the hair fibre to detoxify, protect, and prepare hair for cleansing, ensuring colour lasts longer and hair feels stronger, shinier, and healthier.
Perfect for colour-treated, bleached, or balayaged hair, this treatment is the first step in the Metal Detox routine to maintain salon-quality results at home.

My go to product, love it!
Nice and love the neutral coffee colour
Makes other conditioners feel like duds. This conditioner is truely rich and moisturising, and you don’t need much.
Have been using Kevin Murphy products for many years . Great results, hair always thick and shiny .
Smells good too
Its a beautiful product that supports my post chemo hair
I find using the Lust haircolour for touching up around the edges and parting lines so effective and easy. You dont have to be too careful, just swipe the brush on the colour and then run it over your hair. So easy and it looks completely natural. It will stay in until you wash your hair again
Excellent shampoo. Does not strip hair. Smells great and is not overpowering. Maintains colour well. Excellent price and a little goes a long way. Highly recommended!
This kit has everything you need and it does exactly what it says my hair was not damaged and I achieved a very light shade on medium to dark hair
I’ve been using this shampoo for a while now and love it so much I got my mum to start using it too. We both struggle with dry hair and it’s really helped with that.
I have used Goldwell product for a long time and switch around what I use. But this duo is my favourite especially the conditioner. It’s so conditioning but still lightweight. Makes my hair very combable which is not an easy thing to do. Will definitely repurchase :)
Worth the money, leaves my hair so soft and silky. Easy to apply with the spray bottle but it does take a few minutes to apply.
This product coats roots with a very fine powder mist, giving instant invisible body. There is no visible residue or stickiness and like all Kevin Murphy, it has a delightful fragrance.
Always fantastic service
Great products and service, will be back !
I used the sample of this and just had to buy the bottles it's great I love it makes my hair smooth and frizz free all day
