For anyone who uses heated styling tools on their hair, a good thermal spray is a must have. But finding one that adds some serious body and shine? Well, that's just an added bonus. While Rusk Thermal Shine Spray ($16) is exactly what it claims to be — a heat protector that keeps your hair from frying — what makes it special is that it contains a touch of pure argan oil, making it a powerhouse in the shine department. No added shine-enhancing products are needed once your hair is finished. Just mist down your strands with Rusk's thermal spray before styling, and you'll have hair so lustrous you might not be able to stop running your fingers through it all day.
