At Drybar, a pair of scissors or hair-coloring foil is nowhere to be found. That’s because the business’s founder, Alli Webb, opened the shop strictly for blowouts after her in-home business skyrocketed. Featured extensively in the media—and even prank called by Justin Bieber—each of the more than 25 white-hued, airy shops revolves around a center bar where customers sit for up to 30 minutes as stylists blow-dry, straighten, and curl their hair. From a menu booklet, clients select a cocktail-themed hairstyle, such as The Mai Tai, which imparts beachy waves, and The Manhattan, which streamlines locks with a sleek finish that mimics the straight lines of downtown New York and can be outfitted with a tiny doorman who hails cabs for you. The staff at Drybar also crafts updos, travels on location for an additional fee, and tallies bar tabs so that customers can pay for multiple blowouts at once.
