Simply Stylin’ Silk Serum is made from some of the highest quality pure silicones available. We blend it gently over the course of a day to maximize rather than break down the contributions from each ingredient. In fact, when we blend it this way, we find Silk to be smoother and silkier when applied to the hair. You will find Silk to be a light, smooth serum that can be directed to desired areas of your hair quickly and easily. It is non-greasy with no build-up and has a pleasant clean fragrance.
