I got this from a wwe livejournal community:
Just thought this was interesting, Jericho's website posted a comment from Jericho replying to a fan on the message board. The fan says "In normal life and for acting, i think it is better having short hair, but for Wrestling and being in a band, i think he needs long hair..." Jericho replied with this: "I have short hair now. So does Bruce Dickinson, James Hetfield and Jeff Hardy. We all still rock. Deal with it junior!"
I don't watch wrestling, but Chris Jericho does lots interviews and commentary for various music shows, he seems like a pretty cool guy.
well its probably true that it is easier to get roles for acting and such when you have short hair.
but thankfully, I'm going for something more behind the camera stuff. so hair length doesn't matter for that
