Possibly the most in-demand hair stylist in New York, Hershberger owns the exclusive Meatpacking District salon that bears her name.

Born into a Kansas oil family and raised in California, after Hershberger connected with famed photographer Herb Ritts, the two began building a celeb clientele on the West Coast. But it was creating Meg Ryan's signature shag in 1995 that really landed Hershberger on the (hair) map, as hundreds of thousands of housewives aped the look to disastrous effect. Several years later, she left her home at the John Frieda Salon in West Hollywood and moved to New York, where she opened Sally Hershberger Downtown in the Meatpacking District in 2003. She immediately set the Manhattan salon scene aflutter with her stratospheric prices, charging $600 for a simple cut. Although she temporarily lost the distinction of offering the city's most overpriced hairdo when Orlando Pita priced his cuts at $800, Hershberger has since retaliated and matched Pita's price tag.

Unlike many celeb hair stylists who fawn over their clients and offer up a "You look fabulous, dahling!" every few minutes, Hershberger is notoriously low-key and aloof in person. Double-cross her, though, and you're liable to face her fierce temper. Following a less-than-amicable split with her former business partner, John Frieda, Hershberger reportedly screamed at her staff to throw out every last bottle of Frieda shampoo and conditioner that her salon once carried. Hershberger is gay: The L Word's lady-killing hairdresser, Shane McCutcheon, is widely believed to be based on her. [Image via Getty]
