L’Oréal Metal Detox Pre-Treatment 500ml

L’Oréal Metal Detox Pre-Treatment 500ml – Professional Pre-Colour Hair Detox Spray

L’Oréal Professionnel Metal Detox Pre-Treatment 500ml is a breakthrough professional spray designed to protect the hair before any colour, balayage, or lightening service.

Backed by over 7 years of scientific research and 7 global patents, this innovative formula neutralises excess metal particles in the hair –

especially copper – for up to 87% less breakage during colouring.

Whether you're lifting natural pigment or refreshing a colour, the presence of

metals in the hair fibre can cause unreliable colour results, uneven lift, and increased hair sensitivity. 

These metals build up naturally in hair from water exposure.

Metal Detox Pre-Treatment solves this problem by detoxifying the hair at the fibre level with a patented molecule called Glicoamine,

small enough to penetrate deep and neutralise metal from within.

Why Choose L’Oréal Metal Detox Pre-Treatment 500ml?

Metal Detox Pre-Treatment is trusted by professionals worldwide for its proven ability to reduce colour breakage,

enhance tone accuracy, and prepare hair for optimal colour penetration.

It’s suitable for all hair types and textures and integrates seamlessly into any salon service without adding time to appointments.

What Is Glicoamine?

Glicoamine is L’Oréal’s patented technology, scientifically engineered to target and neutralise metal particles that affect colour performance.

Unlike chelating agents that sit on the surface, Glicoamine is small enough to penetrate the hair shaft, detoxifying from within.
