Detox Pre-Treatment

L'Oréal Professionnel Serie Expert Metal Detox Pre-Shampoo is a professional pre-treatment specifically formulated to be applied to dry hair before shampooing. Utilizing patented Glicoamine technology, it breaks down and traps metal particles (copper, iron, nickel) that accumulate inside the hair fiber from water exposure and pipeline erosion—addressing the hidden cause of breakage, brassiness, and poor color retention .

As the essential first step in the complete 4-step Metal Detox system (Pre-Shampoo → Shampoo → Mask → Leave-In), this treatment prepares hair for optimal cleansing and conditioning by removing metal deposits that can block other products from penetrating the hair fiber. When used as part of the full system, clinical testing shows up to 87% less hair breakage and 100% true-to-tone color results .

Suitable for all hair types, especially those affected by hard water, well water, or old plumbing, this pre-shampoo is an essential tool for anyone wanting to protect their hair from metal-induced damage . For best results, apply generously to dry, unwashed hair section by section, leave for 1-2 minutes, then proceed with Metal Detox Shampoo without rinsing out the pre-treatment .
