KeraSpa shampoo is specifically designed to maintain smoothing treatments with keratin (relaxed, straightened or colored hair). The unique combination of proteins in wheat germ and silk penetrate the hair shaft, providing the moisture needed to strengthen hair while promoting shine. Mineral extracts derived from the sea nourish and soften the hair helping to retain its moisture which makes it more impervious to the weather while protecting the hair cuticles. The hair feels fresh, soft and malleable then become easy to style.
