The 39-year-old actor focuses on his hands and seeks regular treatment for dirty nails, reported Contactmusic.
"I am obsessed with nail cutting. I have had manicures. I have become a bit obsessed about my nails. Playing a sailor in the play 'Anna Christie', I had to shove black make-up under my nails and could not scrub it all out for two months, it was a nightmare," he said.
Law likes to take care of his appearance but does not appreciate when men spend too much time to look good.
"Men should not be too groomed. I love the ritual of getting ready for an event, but you can tell when a guy has been standing in front of a mirror for too long," he added.
