What it is: A three-piece set of haircare products that together work as salvation for dry or damaged hair. What it does: Restore Shampoo, Conditioner, and Mask Treatment are 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 percent. 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 so that hair looks and behaves like gorgeous "virgin" hair. This set contains: 2 oz Restore Shampoo. 2 oz Restore Conditioner. 1 oz Restore Mask Treatment. What it is formulated WITHOUT: Parabens. Sulfates. Phthalates. What else you need to know: Virgin hair has a protective layer that is completely intact, which is why it is in such great condition. But frequent washing, heat styling, and processing damages this protective layer. Hair becomes very porous and unable to seal in moisture. Living Proof scientists discovered a way to restore that protective layer and reduce hair's porosity. And because Restore can do this without weighing hair down, it helps stop the cycle of dryness and damage. Research results: After 5 uses of Restore Shampoo and Conditioner, hair's porosity is reduced 100%. After 5 uses of Restore Shampoo and Mask Treatment, hair is 9 times more resistant to breakage.
