What it is: An ultra-lightweight revitalizing spray that instantly polishes and perfects dry or damaged hair, while defending against heat and UV damage from cuticle to cortex. What it does: Restore Revitalizing Spray features a proprietary complex of pro-vitamins, UV absorbers, and PolyfluoroEster to instantly add shine, smoothness, and polish while increasing hair"s resistance to breakage. Safe and effective on color and chemically processed hair, it can be used on both wet and dry locks. What else you need to know: Heat and UV are major culprits of damage. Heat tools are hotter than ever, some reaching 450°, which is twice as high as the boiling point of water. This heat, applied to wet or dry hair, "boils" the water content of the hair, causing fractures in the cuticle?hair"s defense layer.
