Our dermatologically tested and laboratory proven treatment conditioner leaves hair 68% stronger after just one use, when paired with Give Me Strength Strengthening Shampoo and Scalp Concentrate. HAIR GROWTH: Active ingredients Sweet White Lupine and Rosemary Oil encourages cell metabolism and circulation at scalp level, boosting new hair growth, whilst blocking the hormone responsible for hair loss (androgenic alopecia). HAIR DENSITY: The keratin-rich formula harnesses wheat proteins and vitamin B3, which rebuild the surface of the hair for greater density. REDUCED BREAKAGE: Deeply hydrating ingredients, including coconut oil and camellia seed oil smooth and soften dry, damage strands, increasing elasticity so that flex rather than snap.
