Nothing screams summer like loose, beachy waves. The breezy, warm-weather hairstyle has appeared on the runway for years, adding a textural contrast to the feminine and sophisticated aesthetics of designers like Alexander Wang, Thakoon, and Diane von Furstenberg. “They’re low maintenance,” InStyle Beauty Director Kahlana Barfield says on why she loves the look. “It looks really easy and effortless, and not too overdone.”

But how does one score the sexy, lived-in style stars like Gisele Bundchen and Kate Hudson have perfected? According to Barfield, it’s all about your hair type and of course, a few mists of texturizing spray for that coveted tousled appearance. If you have fine hair, for example, it’s quite simple. “You can wash your hair, let it air dry and put a little beach spray,” she says.
