Restore Mask Treatment is an intensive weekly treatment for dry and damaged hair. Restore Mask weightlessly nourishes each strand, increasing strength and manageability, leaving hair soft, shiny and smooth. Restore Mask Treatment is formulated with Living proof®'s moisture-controlling molecule, PolyfluoroEster, to restore the protective layer on dry or damaged hair and reduce hair's porosity by 100%. The end result is hair's porosity is normalized to be like virgin hair. Restore also increases hair's resistance to breakage up to nine times while healing, protecting and preventing further damage. Strength, smoothness, shine and body are restored. Restore Mask Treatment is safe for color and chemically treated hair.
