In 2008, after five years as a stay-at-home mom, hairstylist Alli Webb was ready for some grown-up time. She startedtravelingfrom home to home in Los Angeles, providing affordable blowouts (that's a wash, a dry and a style, gentlemen) to other moms who, like her, were eager for a small break from nonstop responsibilities. Nearly a decade later, Webb's brainchild has grown intoDrybar, a blowouts-only salon chain beloved by women across the country. The bar-themed business -- styles offered include the Cosmo (loose curls) and the Mai Tai (beachy waves) -- is chic and girly, and serves up as many mimosas as hairstyles in a given day.
