"Hair fiber is made up of bonds that give it strength. Hair color, chemicals, pollution, heat and daily styling can damage bonds leaving hair weak, dull and dry. The Repair Bond™ system* is formulated with Rescuplex™: a complex clinically proven to rebuild and maintain hair’s damaged disulfide bonds. This concentrated mask infuses maximum hydration while restoring damaged hair. It penetrates deep into the hair fiber to reinforce damaged hair bonds and helps to protect from future damage, all while smoothing the cuticle to alleviate frizz, boosting shine, softening and reducing color fade. Blended with Rice Bran Oil, Rosemary Oil, Hydrolyzed Quinoa and Vitamin C for improved moisture, elasticity and shine. For all hair types. Vegan, Cruelty-Free, Paraben-free, Sulfate-free, Phthalate-free. *Based on a system of Repair Bond +Rescuplex™ Shampoo, Conditioner, Leave-In Treatment and Mask. "
