While we’re meant to believe that the enviable locks on the heads of all our favorite It girls are the result of solid genetics and/or a decent hair brush, we all know that is just not the case. No, every fashion girl knows that behind every A-list hairstyle, there’s a wizard making magic happen. And, these days, the wizard du jour is Jen Atkin. The hair guru has unquestionably taken the beauty industry by storm, with her robust roster of celebs that seems to be ever-growing, and she constantly rolls out new products to keep our tresses in tact via her Ouai haircare line. Most recently, she made her mark on Paris Fashion Week by styling the manes of just about every It girl you can imagine. From top knots to effortless waves, take a look at our favorite looks created by the great and powerful Jen.
