As the preferred hairstylist of Gigi Hadid, Chrissy Teigen, and Poppy Delevingne (just to namedrop a select few), Laura Polko essentially has the Hollywood monopoly on cool-girl hair—and in 2017, that means foregoing too-polished, wide-barreled waves in favor of something a little more effortless and a little less "done." In fact, Polko doesn't even technically categorize her textured, surfer-esque locks as "waves"—they're bends.
