For some reason I don't think it's really his hair we're taking about, well yes, it is...but I think the issue here is familiarity. I mean, we've always seen Lorne with with long hair and a mustache and now that he's suddenly changed it, we're all like; 'Whoa, what's this!?'
People don't like change, makes them wonder what else is going to change...and now that I've gone waaaay too deep, I think I'll leave...
PS. He's looks great either way...
