What do Gigi Hadid, Kaia Gerber, Chrissy Teigen, and Hailey Baldwin all have in common—aside from impeccable genetics, of course? That would be Laura Polko, who might as well be the official hairstylist of Hollywood's cool crowd. You already know just by following her It clientele on Instagram that Polko specializes in hair that looks simultaneously effortless and polished—it's that exact kind of NYC-meets-L.A. ethos that Hadid herself embodies, after all.
So what does one of the most in-demand stylists of the moment always have on hand? We had to ask Polko for a peek inside her bag for our series Just Five Things. Among her must-have products: Color Wow Root Coverup ($35), a drugstore hair spray, and a spool of black elastic, which we didn't even know existed. (Think of it as one very long hair tie.) Check out the rest in the video below.
