Brace yourselves, X-Men fans: a staple of the comic books may be emerging in director Bryan Singer’s upcoming sequel X-Men: Apocalypse. Ever since James McAvoy was first cast as the young Professor X in X-Men: First Class, fans have been asking when he’ll be taking on Charles’ signature Mr. Clean-esque hairstyle. It’s kind of a silly thing to harp on (does it really matter that much if Professor X has hair or not?), but following the events of the recent X-Men: Days of Future Past, it appears that the character may start to look more like his comics counterpart, as McAvoy recently said he thinks Apocalypse is when his character will finally go bald. More after the jump.
