Don't Miss:

Gossip Girl returns tonight with its sixth and final season! And while we hope all secrets will be revealed—who is Gossip Girl!?—we uncovered the secret behind Blake Lively’s perfectly tousled tresses thanks to the show’s hairstylist Liz Reilly. “It’s honestly quite easy,” Reilly told InStyle.com. “Her long, beachy waves are a look that we’ve been doing since the beginning.” For the piecey, high-volume look, Reilly relies on her secret weapon: Oribe Dry Texturizing Spray ($39, oribe.com). “Spray the texturizer at the root of dry hair for a nice lift and hold,” she told us. “To get Blake’s look, I generously use the spray then roll her hair into a bun and let in set.” Then, after a few minutes and a light veil of hairspray, she lets the bun loose and rakes fingers through the strands.
