Drybar founder Alli Webb turned blowouts into a booming business. Since 2010, Webb, who runs the company with her brother, Michael Landau and her husband, Cameron Webb, has opened 30 blow dry salons (no cuts, no color) across the country, serving up a streamlined menu of styles to some 100,000 customers a month. They're on track to hit $40 million in revenue this year, thanks also to a new line of styling products and tools, which beauty retailer Sephora picked up in an exclusive deal.
