Intense Hydration

L'Oréal Professionnel Serie Expert Metal Detox Hair Mask is a professional hydrating mask specifically formulated to lock out harmful metal particles found in water, protecting hair from metal-induced color fading and damage . Powered by patented Glicoamine technology—the only active agent small enough to trap and neutralize metals inside the hair fiber—this mask helps prevent breakage and ensures 100% true-to-tone color results .

When used as part of the complete Metal Detox system, clinical testing shows up to 87% less hair breakage . The formula intensely nourishes dry, bleached, and color-treated hair, leaving it soft, shiny, and easier to detangle with a smooth, healthy appearance . It is suitable for all hair types and textures, including dry, thick, or curly hair, and delivers intense care without weighing hair down .

The 500ml professional size is ideal for salon use and long-term home care, especially for those with bleached, highlighted, or color-treated hair who want to protect their investment and maintain vibrant, healthy hair between salon visits . For best results, apply evenly on clean, towel-dried hair after using Metal Detox Shampoo, leave on for 1 minute (or longer for deeper conditioning), rinse thoroughly, and follow with Metal Detox leave-in cream or oil .
