MATRIX Metal Detox Pre-Shampoo for Hair Repair — Pre-Wash Treatment to Strengthen Fibers & Reduce Metal Damage

MATRIX L'Oréal Professionnel Metal Detox Pre-Shampoo is a salon-grade pre-wash treatment that strengthens hair fibers and seals micro-breaks to reduce metal-driven damage and excess water absorption.

If your hair feels fragile, porous, or more prone to breakage after swimming, city water, or multiple color services, this Metal Detox Pre-Shampoo works before you cleanse to reinforce the fiber and reduce the hair’s tendency to soak up metallic contaminants. Designed to be used prior to shampoo and mask, it creates a protective layer that helps hair stand up to water with dissolved metals and everyday mechanical stress.

How does this pre-shampoo protect hair from metal in water?

The formula targets micro-breaks and porous zones along the hair shaft so fewer metals are absorbed during washing, swimming, or exposure to hard water. By filling small gaps, it reduces the pathways metals use to penetrate the fiber, lowering cumulative damage over time.

• Refills micro-breaks to limit metal entry into the cortex.
• Creates a smoother surface that reduces metal adsorption.
• Used before shampooing to block metal exposure during cleansing.

What improvements can I expect after a single use?

In clinical-style testing, hair treated with this pre-shampoo shows markedly lower breakage and a stronger fiber profile after just one application. Expect hair to feel less brittle, more cohesive, and noticeably smoother when combined with the matching shampoo and mask.

• Significant reduction in breakage measured after one use.
• Perceptible increase in smoothness and manageability.
• Works best as part of the full Metal Detox routine (shampoo + mask).

How do I use Metal Detox Pre-Shampoo for best results?

Apply on dry or slightly damp hair before cleansing: distribute through lengths and ends, leave on according to the product directions, then rinse and follow with Metal Detox Shampoo and Mask. Because it’s a pre-wash step, it prepares the fiber so subsequent products can perform more effectively.

• Apply on dry or towel-damp hair before shampooing.
• Massage through lengths and focus on porous areas.
• Rinse and continue with Metal Detox Shampoo and Mask.

Will this make my color-treated or chemically processed hair feel different?

The treatment is formulated to strengthen and fill micro-damage, which helps chemically treated or color-treated hair feel more resilient and less porous. It does not replace color care products but is compatible with them to minimize metal-driven weakening that can affect finish and longevity.

• Helps color-treated hair feel stronger and less porous.
• Compatible with salon color and chemical services.
• Best results when paired with the Metal Detox Shampoo and Mask.

Who is this for? MATRIX L'Oréal Professionnel Metal Detox Pre-Shampoo is aimed at anyone whose hair is exposed to metals in water—swimmers, people on hard-water supplies, and clients who frequently color or chemically process their hair. It’s especially useful for fragile, porous, or chemically treated hair that needs an upfront protective step to reduce breakage and improve the efficacy of subsequent cleansing and conditioning products.
