ISAIAH WASHINGTON

Playing a doctor on Grey's Anatomy doesn't require taking the Hippocratic Oath. Still, Washington, 42, follows a "first do no harm" policy with personal grooming. No scruffy beards: "What woman in her right mind wants to be stuck by a dude with a bunch of bristly hairs?" No gnarly nails: "I get manicures and pedicures." No designer haircuts: "A trim once a week. As natural as possible – not too tapered or Jheri-curl juicy."
