Playing a doctor on Grey's Anatomy doesn't require taking the Hippocratic Oath. Still, Washington, 42, follows a strict "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? I don't care how cute he is."

NO GNARLY NAILS: "I get manicures and pedicures. Gotta keep the feet straight. Wifey will put me in the doghouse if they're not."

NO DESIGNER HAIRCUTS: "A trim once a week. As natural as possible—not too tapered or jheri-curl juicy."
