Kevin Murphy Everlasting Colour Leave-In is a lightweight, bond-building leave-in spray designed to enhance the longevity and vibrancy of colour-treated hair. Its acidic pH formula helps seal the hair cuticle, preserving colour and protecting against environmental stressors. Infused with nourishing ingredients like Hydrolyzed Vegetable Proteins and Moringa Oleifera Seed Extract, it strengthens, hydrates, and detangles hair, leaving it smooth and manageable.
