This lightweight protection spray from Nanoil shields hair from the heat of a flat iron, blow dryer, and curling rod. By creating a protective coating, it increases hair’s resistance to damage from hot styling. It also prolongs the lifespan of hair color by preventing the fading caused by both hot styling tools and sun exposure. Silk proteins, which Heat Protectant Spray is formulated with, boost smoothness, nourishment and glossiness. Nanoil provides protection against temperatures of up to 430℉/220℃!
