Your Colour Isn't Failing. Your Water Is Contaminating It.

Copper and iron ions from water enter your hair with every wash. When they mix with colour and bleach, results become patchy and unpredictable — through no fault of the formula or stylist.

The L'Oreal Professionnel Metal Detox System

Metal Detox is a 5-product system with two protocols: a home maintenance routine (shampoo + mask + oil, used every wash) and a professional pre-service treatment (Pre-Treatment spray, used before every colour, balayage, or lightening appointment). Both use Glicoamine as the active — the only chelating agent small enough to penetrate the hair fiber and neutralize metal inside the cortex.

FAQ

Why does my bleach go patchy or uneven?

Patchy, uneven bleach lift is one of the most common presentations of metal contamination in hair. Copper and iron ions — deposited inside the hair fiber from municipal water and copper plumbing — react with the oxidants in bleach and lightener during the service. This reaction is uneven across the hair shaft because metal concentration varies section to section, strand to strand, depending on each strand's porosity and exposure. Where metal concentration is higher, the oxidant reaction is disrupted, resulting in sections that lift less, go brassier, or achieve different tones than adjacent sections despite identical product application. The professional protocol for preventing this is L'Oréal Professionnel Metal Detox Pre-Treatment Spray (10% Glicoamine) applied to dry hair before every lightening service. Glicoamine neutralizes metal ions inside the fiber before they can react with bleach oxidants — restoring the predictability and consistency of the service result.

What is Glicoamine and how does it work in hair?

Glicoamine is a patented chelating molecule developed by L'Oréal Professionnel specifically for hair metal contamination. A chelating agent is a molecule that binds to metal ions and renders them chemically inert — preventing them from reacting with other substances. What makes Glicoamine unique is its molecular size: it is small enough to penetrate the hair fiber and reach metal ions inside the cortex, where other chelating agents cannot reach. Once inside the fiber, Glicoamine tracks, binds to, and neutralizes copper and iron ions — preventing them from reacting with the oxidants in colour and bleach services. In clinical testing, Metal Detox with Glicoamine delivered 99% less breakage in one use, 87% less breakage risk as a pre-service treatment, and 100% true-to-tone colour results. Glicoamine is present across the full Metal Detox range — Pre-Treatment Spray, Anti-Metal Shampoo, Professional Mask, Leave-In Cream, and Concentrated Oil — providing both acute metal removal and ongoing protection against re-accumulation.

How is L'Oréal Metal Detox different from Kérastase Première?

L'Oréal Metal Detox and Kerastase Premiere both address water-related hair damage, but they treat completely different contaminants. Metal Detox (Glicoamine) addresses copper and iron metal ions that penetrate the hair fiber from water and oxidative services — the primary symptom is colour instability, patchy bleach, and service-related breakage. Kérastase Premiere (Citric Acid + Glycine) addresses calcium and magnesium mineral deposits from hard water — the primary symptom is hair stiffness, rigidity, brittleness, and dullness that doesn't respond to conditioning. Both contaminants come from water, but they are chemically distinct and require different treatments. In older Vancouver buildings with copper plumbing and hard water, both forms of contamination are often present simultaneously — using both systems together is the complete professional protocol for water-contaminated hair.

Does everyone need Metal Detox or just people who colour their hair?

Metal contamination from water is universal — everyone who washes their hair in municipal water accumulates some level of metal in their hair fiber. However, the consequences are most significant for clients who colour, bleach, or use oxidative hair services, because metal ions react with service oxidants to create unpredictable results. For clients who don't colour, metal contamination still causes increased breakage (particularly in porous hair, which absorbs 2x more water and metal), reduced smoothness, and accelerated damage in heat-styled hair. The home maintenance system (Anti-Metal Shampoo + Mask + Oil) benefits all hair types. The Pre-Treatment Spray is specifically for clients receiving colour or lightening services. For coloring clients in Vancouver with copper plumbing — the pre-treatment before every service is not optional if consistent, predictable results are the goal.

How often should I use L'Oréal Metal Detox?

The recommended usage protocol for the L'Oréal Professionnel Metal Detox system: Anti-Metal Shampoo — every wash (replaces regular shampoo). Professional Mask — once or twice weekly after shampooing (1 minute leave-in for maintenance, 15 minutes for intensive treatment on bleached hair). High Protection Cream or Concentrated Oil — daily on towel-dried or dry hair, lengths to ends. Pre-Treatment Spray — before every colour, balayage, or lightening service. For clients in older Vancouver buildings with copper plumbing or those who bleach frequently, this full protocol is recommended as an ongoing routine rather than a temporary course of treatment. Metal re-accumulates with every wash in a metal-contaminated water supply — consistent ongoing use prevents re-accumulation rather than repeatedly treating the problem after the fact.

Can Metal Detox be used on color-treated and bleached hair?

Yes — Metal Detox was designed specifically for colour-treated and bleached hair, which is the highest-priority group for metal contamination management. The Anti-Metal Shampoo is sulfate-free and colour-safe, formulated to protect colour longevity while removing metal particles. Clinical testing of the full system demonstrated longer-lasting colour, 2x shinier results, and 100% true-to-tone colour consistency. For bleached hair specifically: bleached and lightened hair is the most porous hair type, which means it absorbs 2x more water — and 2x more metal — than unprocessed hair. This makes the ongoing use of Metal Detox maintenance products particularly important between lightening services, not only at the service itself. The Professional Mask provides 100 hours of nourishment specifically for dry and bleached hair while protecting against metal re-accumulation.

My hair color looks different than expected — could it be metal contamination?

Yes — metal contamination is one of the most common and most frequently overlooked reasons for unpredictable colour results. Signs that metal contamination may be affecting your colour: the result is warmer, brassier, or more orange than the formula should produce; colour fades unusually quickly; bleach lifts unevenly across sections of the head; colour doesn't match the target shade despite correct application; highlights look inconsistent from foil to foil. These outcomes happen when metal ions inside the hair fiber react with colour or bleach oxidants during the service — disrupting the expected chemistry. L'Oréal Metal Detox Pre-Treatment Spray (10% Glicoamine) applied before the service neutralizes metal before it can react. For clients who have experienced repeated unexpected colour results despite professional application, Metal Detox pre-treatment is the professional intervention that restores predictability.
