(InStyle.com) -- Ever wonder how actresses like Sienna Miller look stunning 24/7? Good genes, sure. But they also get a little help from their friends Sienna Miller and favorite hairstylist Adir Abergel: "If I worried what people thought about my look, I'd get it all wrong." Sienna Miller and hairstylist Adir Abergel Try to talk coifs with Sienna Miller and she'll cut you off at the pass. "I don't even own a hairbrush!" she insists. "I'm really not too attached to my hair." No kidding. She gamely lopped off about 10 inches to play Edie Sedgwick in Factory Girl. But the actress is much less keen to part with her hairstylist Adir Abergel, for whom she has been known to cook dinner at her London home.
