Hair is almost entirely made up of protein, which gives hair its strength. ALL NEW, paraben-free Fructis formulas with Active Fruit Protein™, an exclusive combination of citrus protein, Vitamins B3 & B6, fruit & plant-derived extracts and strengthening conditioners, are designed for healthier, stronger hair. Fructis Moisture Lock with Cactus Extract locks in 48 hours of moisture* into normal to dry hair with every wash, while strengthening strands to help prevent moisture loss & help resist chronic dryness from frequent shampooing. Hair feels weightless, softer and looks shinier, even after washing up to twice a day! *With shampoo, conditioner & leave-in treatment.
