TRESemmé Thermo Sculpt Memory Shampoo gently cleanses weak fibres, creating the perfect foundation for stronger, more resilient strands. Powered by Salon Grade Thermo-Activated KeraKinetic Tech, this professional-quality formula transforms the way hair responds to heat. Activated by heat-styling, crystal-like molecules re-form in the core of the hair, enhancing resilience and the ability to retain style*. Apply a generous amount of shampoo to wet hair. Gently massage the scalp with your fingertips to work into a lather, then rinse thoroughly.
