L'Oréal Professionnel Serie Expert Metal Detox Mask 75ml is a nourishing treatment designed to protect color-treated and sensitized hair from metal particle accumulation. Infused with Glicoamine, a molecule small enough to penetrate the hair fiber, it neutralizes metal particles like copper, reducing the risk of breakage and color fading. The creamy formula, enriched with ingredients such as Cetearyl Alcohol, Amodimethicone, and Tocopherol, smooths and softens hair, enhancing shine and manageability. Ideal for use after coloring, balayage, or lightening services, this mask helps maintain vibrant, long-lasting color while strengthening the hair structure. Apply to towel-dried hair, leave on for 1 minute, and rinse thoroughly.​
