ECRU New York combines high quality skincare and cosmetic grade ingredients with the performance of professional haircare. Silk proteins are the highest grade protein ingredients that are created from the hydrolysis of silk fibers. They are actually "the inner part" of silk removed during this process. Originally, this ingredient was only used in high-grade skincare, however when applied to hair, silk proteins form a transparent protective film that seals the hair cuticle increasing elasticity, natural shine and further preventing damage to the hair. Ecru New York was created to "Treat and Perform". Silk proteins are used in every product within the collection because they strengthen and improve the integrity of the hair.
