Metal Detox: How Does it Work?

You may never have thought about it before, but the very water you use in your salon could be impacting your colour, balayage, and lightening results. After 7 years of research, L’Oréal Professionnel have discovered that excess copper found in water can leave hair more prone to breakage during colouring and pre-lightening and can directly impact colour vibrancy.

The level of metals found in the hair varies depending on water quality and hair porosity but, wash after wash, these metal particles can accumulate inside the hair fibre. While excess metal does not pose any health risks, contact with oxidants and colour during salon services can lead to breakage and unreliable colour results.

That’s where Metal Detox comes in!

To tackle this problem, L’Oréal and a team of experts discovered Glicoamine. This breakthrough molecule penetrates deep within the hair fibre and neutralises metal where it is located.

Thanks to our collaboration with the Ioannina University, we identified a perfect molecule: Glicoamine. It is the only active agent small enough to trap and neutralize metal inside the fiber. Fiber integrity is preserved and the oxidant gets to fully do its job

The result? Serie Expert Metal Detox offers a 3 step professional protocol to eliminate metal build up, dramatically minimising the risk of breakage by 87%* and ensuring a reliable colour result every time.

Metal Detox Pre-Treatment

Used prior to colouring and lightening services, this professional pre-treatment targets and neutralises copper deposits found in the hair fibre for a reliable colour result with no effect on processing times.

Spray onto dry hair from root to tip, applying 8-10 pumps on short hair and 15-20 pumps on medium-long hair, focussing on the lengths. This Pre-Treatment can be used with other colour and lightening brands.


Metal Detox Shampoo

The creamy, sulphate-free Metal Detox Shampoo gently removes excess copper from the hair after colouring and lightening services.

Apply evenly onto wet hair and lather to a rich foam. Repeat as required.

Metal Detox Shampoo is available in salon-sized 1.5L bottles and retail-sized 300ml bottles to maintain metal neutralisation at home.


Metal Detox Mask

The innovative Metal Detox Anti-Deposit Mask is the essential final step in the regime. The nourishing treatment provides intensive care while defending the fibre against future metal deposits.

Apply evenly onto cleansed, towel-dried hair and leave for 15 minutes. Rinse thoroughly.

Metal Detox Mask is available in salon-sized 500ml tubs and retail-sized 250ml tubs to protect against metal build-up at home.
