RATED GREEN Real Argan Smoothing Serum for damaged hair is an ideal silicone serum for hair after chemical and thermal treatments, but at the same time thin and prone to weighing down. Easily washable with water, silicones provide protection against external factors and will also serve as thermal protection. In turn, argan oil adds shine, elasticity and strength to the hair, and glycolipids increase oil absorption and regenerate the CMC layer of the hair.
