What it is: A hair serum that helps reinforce and strengthen fragile hair from the inside out, hydrating strands and locking in moisture, enhancing softness.What it does: This serum forms a scaffold around each hair fiber to help protect from external aggressors. It also helps prevent breakage and hair fallout caused by brushing and styling, encouraging growth over time. The serum also improves the tensile strength and elasticity of each hair strand. The serum is formulated with Oribe's Signature Complex of watermelon, lychee and edelweiss flower, which help defend hair from oxidative stress, photoaging and the deterioration and color-depleting effects of the elements. A curative blend of chia seed, bio-fermented bamboo and plant-based protein penetrate the hair cortex to build strength from within. Additional ingredients help rehydrate and strengthen, enhance shine, promote elasticity to prevent breakage and add softness to each strand. Made in the USA
