Does John Travolta wear a wig, or did he get a hair transplant? Did the chicken or the egg come first? Well, no hair transplant ever came, so it must be a toupee! John Travolta has tried to recapture the glory of his Grease days by maintaining a respectable hairline, but he problem is that it's so obviously unnatural. He's tried dyes, nettings, different lengths, and it always seems to be indicating of a hairpiece. It's odd that he wouldn't even consider getting a hair transplant.
