THE EXPERT Colorist Michael Murphy has tended to the manes of Katie Holmes, Celine Dion and Ivana Trump. One of his most challenging color changes came a few years ago when he had to change Holmes's hair from a red hue to her original brunette in 24 hours. "She was a trooper and we pulled it off perfectly," he says.
