TRESemmé Keratin Smooth Shampoo is a professional-inspired cleansing shampoo formulated for frizzy, unruly and difficult-to-manage hair that needs lasting smoothness and control. The formula is enriched with Argan Oil and Hydrolyzed Keratin to care for the hair while improving its smooth, polished appearance. Argan Oil provides nourishing conditioning care that supports softness and shine, while Hydrolyzed Keratin conditions the hair fibre and improves the feel of rough or damaged-looking strands. Dimethiconol coats and smooths the hair surface to reduce roughness and enhance manageability, while Guar Hydroxypropyltrimonium Chloride provides additional conditioning for a softer hair feel. The shampoo effectively cleanses away everyday impurities, excess oil and product buildup while preparing hair for conditioning and styling. Designed to deliver professional-quality smoothness, the formula provides up to 72 hours of frizz control, leaving hair feeling cleaner, smoother, softer and easier to manage. It is ideal for incorporating into a regular smoothing hair care routine, particularly for hair prone to frizz, flyaways and an unruly texture.
