The heat is on! TRESemmé Keratin Smooth Blowout Spray seals in smoothness and shine while shielding your hair against the damaging effects of heat styling. Heat causes damage, breakage, split ends and dry hair. Our Keratin Smooth Blowout Spray preps and protect your strands up to 450°F. Our formula is designed to enhance hair's flexibility and help it hold its shape, all while fighting the heat. This lightweight spray also gives your hair softness and shine, so you can style away. Perfect your Smooth Blowout in 3 easy steps. Prep strands with Keratin Smooth Shampoo and Conditioner, then style with Keratin Smooth Blowout Spray. Hold the bottle 6-8 inches away from your head and spray it liberally onto damp or dry hair before applying heat. Finish with our Keratin Smooth Anti-Frizz Hairspray. Pro tip: when blow-drying, make sure the nozzle of the hair dryer is pointing downward to get extra smoothness. Our unique formulas are PETA-approved and made with carefully selected ingredients, and TRESemmé never tests on animals. We're always made with intention and inspired by the latest trends and style.
