Suave Professionals Keratin Infusion Smoothing Conditioner was created for those with unmanageable hair in mind and was specifically formulated with Keralock Technology. This advanced technology behind Professionals Suave Keratin Infusion Conditioner infuses keratin and seals the hair cuticle from the outside. Created for those with frizzy hair, this smoothing conditioner leaves hair soft, smooth and shiny after every use. Natural keratin protein in hair depletes over time, leaving it unmanageable, frizzy and harder to style, so Suave Professionals Keratin Infusion Smoothing Conditioner contains keratin and seals the hair cuticle. This not only results in more manageable hair for those who use this keratin hair conditioner but it provides frizz control for up to 48 hours, which gives you smooth and healthy-looking hair.
