Veteran actor Christopher Walken likes to pull his hair every day, after reading the practice makes going bald less likely. The Hairspray star credits his distinctive hairstyle with regular yanking at his locks, which he read was what late U.S. President John F. Kennedy used to do as well. He says, "President Kennedy had this great hair, and I read that somebody came and massaged him because he had that back problem, but he would also get his hair pulled. "As men get older, the skin on their heads tightens and the blood gets constricted. Apparently, if you keep your scalp skin loose, you're more apt to keep your hair. "So I just grab it with both hands and yank on it while I'm watching the news."
