John Travolta might have the worst wig in all of Hollywood. He's refused plastic surgery or a hair transplant and instead wears an odd looking toupee. This before and after photo shows him completely bald. It's weird how sometimes he's seen in public with a wig on, and sometimes he totally bald. He's probably lost too much hair which means a hair transplant wouldn't be an option though. It would take a LOT of hair follicles to fill in his scalp, and he probably doesn't have that many donor hair on the back of his scalp.
