TRESemmé 24 Hour Volume Collagen Shampoo is a volumizing cleanser developed for flat, fine or limp-looking hair that needs added body, bounce and movement without feeling weighed down. Its professional-inspired formula contains Hydrolyzed Collagen, a conditioning ingredient incorporated to support fuller-looking, more manageable hair while maintaining a lightweight feel. The cleansing system combines Sodium Laureth Sulfate and Cocamidopropyl Betaine to remove everyday dirt, excess oil and product buildup from the scalp and hair, creating a refreshed foundation for volumized styling. Polyquaternium-10 provides conditioning benefits that improve softness and manageability, while Polyvinylpyrrolidone and VP/Methacrylamide/Vinyl Imidazole Copolymer contribute to the formula's styling and body-enhancing performance. Designed to deliver all-day volume and bounce, the shampoo cleanses effectively without leaving hair feeling heavy, making it particularly suitable for hair that tends to appear flat or lacks natural body. Regular use as part of a volumizing hair care routine leaves hair feeling clean, lightweight and refreshed with a fuller, more lifted appearance.
