Julia's dirty little secret

Julia Roberts says the secret to having good hair is not to wash it - sometimes for up to two weeks. The Closer actress says she loves the way certain stylists do her hair so much that she tries to preserve the 'do - by not washing it. "One of the tricks I've learned over the years is that I can milk a great style to the last possible second," Roberts says. "Honestly, after [my stylist] does my hair, I won't do anything to it for - wait for it - two weeks. My hair doesn't get greasy very fast, so I can go a good ten days without washing it."
