Think it's just your skin that needs hydration? Think again! Water makes up 25% of our hair, but styling, heat and sun can dehydrate it, resulting in lifeless, lacklustre locks. But with our Advance Techniques Hydra Boost Leave-In Treatment, you can treat your parched scalp and weak strands to 8x the hydration.*
