What it is: A deeply moisturizing repairative mask and leave-in treatment that nourishes and repairs hair.What it does: The mask strengthens hair by reducing hair breakage through multiple washes. The mask is formulated with the brand's exclusive Caviar Bond Enforcing Technology to repair and protect hair, reduce breakage by more than 99% and add strength. It is formulated with maracuja oil, known for being deeply nourishing for hair that needs to regain moisture, smoothness and shine. The Caviar Bond Enforcing Technology also helps seal hair cuticles that have been damaged through chemical processes or physical stress. Bond enforcing molecules detect cracks and fissures in the cuticle and fill them, locking the cuticle down, smoothing the hair fiber and decreasing friction. How to use: Shampoo, do not condition. Work through towel-dried hair from mid-lengths to ends, one pump at a time. Do not rinse out. Blow dry or diffuse into hair. For extra care between washes, apply onto dry hair two times a week.
