Gwyneth Paltrow isn't just an Oscar-winning actress. This year she invested in the nation's largest chain of blow-dry bars, Blo, with 50 locations and plans to add 30 next year.

She's not just an investor; she's involved in shaping the look of the salons and the services they offer. "I think my strengths are in anything aesthetic so the look of the salons, trends, social media," said Paltrow.
