Developed by Olie Re Paris laboratories, this lightweight hair serum is formulated for color-treated and chemically processed hair, including hair damaged by coloring, bleaching, or heat styling tools. Powered by a nourishing complex of 11 natural oils, the serum helps improve the look of dry, damaged hair while smoothing the hair shaft and reducing the appearance of split ends. Hair feels softer, more manageable, and visibly shinier with a silky, polished finish. The formula is free from parabens, Sls, and Sles, making it suitable for frequent use on fragile, treated hair without weighing it down.
