Bis-Aminopropyl Dimethicone provides conditioning, softening, improved combability and manageability to hair. It actually bonds to damaged areas on the hair’s cuticle and makes the hair feel softer. It also creates the protective barrier like other silicones and provides easier combing. What makes it different from other silicones is that it does not cause buildup. It will provide conditioning to damage areas and will increase the color-retention.
