"A great blow-dry is a template for everything you want to do with your hair and will keep you frizz-free," says celebrity hairstylist Larry Sims. His technique for getting a perfect blow-out like Beyoncé's? Apply a smoothing serum to wet hair, and then dry out at least 60 percent of the moisture. Next, use a round brush to dry section by section, nape to crown. To keep your blow-out looking flawless, "sleep with a silk bonnet on," he says. "Fantastic!"
