Logan: 22 WTF Moments In Wolverine's Final Stand

20. Wait... Xavier Has Hair?!

It didn't look a great deal like it in some of pre-release marketing materials, but Professor X has hair - wispy and sparse though it may be, but it's definitely there.

But Xavier shouldn't have hair, since X-Men: Apocalypse established that he lost his hair thanks to the villain's attempt to steal his body. Quite why taking on Apocalypse's powers leads to total hair loss (though not eyebrows) remains unexplained, but it's very firmly established that his baldness isn't merely a fashion statement.

So how the hell did it grow back?
