Overview
Color treated hair owners in hard water areas get a one minute mask from L'Oreal Professionnel that clears metals and adds weightless nourishment. It helps color stay vibrant and blocks particles in water from entering the fiber.
Removing metal buildup helps color last and hair feel less brittle after every wash. The full benefit relies on using the matching Metal Detox shampoo too.
Who it's for
People with colored hair, especially in areas with mineral heavy water, who want quick weekly care. Those wanting an intensive repair soak should look at longer treatments.

Performance notes
Breakage drops because the formula removes metal particles that react during coloring and weaken the fiber. Even application on towel dried hair helps it reach every strand in the short wait time.
