The TRESemmé Keratin Smooth System is a salon shampoo and conditioner designed with Lamellar-Discipline™ technology formulated to transform your frizzy, unruly hair into a smooth, sleek look for up to 72 hours* system vs. non-conditioning shampoo. Made with keratin for smooth, shiny manageable hair, this keratin hair treatment is infused with marula oil to seal down the cuticle and prevent humidity from penetrating the hair for ultimate frizzy hair control. To use, apply a generous amount of shampoo to wet hair. Massage gently from roots to end to work into a lather. Rinse thoroughly. Follow with TRESemmé Keratin Smooth Conditioner.
