John Travolta Now: With or Without Hair?

As Dlisted's Michael K noticed, "the other day [John Travolta] looked as bald as HoHan's punane and now he's back to wearing plugs or Tommy Girl's pubic hair on his head. He was obviously wearing a bald cap the other day. Unless, he planted some barley seeds on his head, Xenu pissed on it and hair magically grew!"

The first photo was taken only four days after the second one.  What is up, John?
