What about hair grooming?

Do any of you have prohibitions? During a playoff game that I attended last season one of the officials from a neighboring association wore a ponytail. I'm not kidding.
In my association's bylaws it is "recommended" that we officials not have any facial hair with the exception of a mustache. Me and several other officials wear goatees in the offseason so we were joking about changing the rule. However, I shared the story about the ponytailed official. We can't wear a perfectly manicured goatee but that guy can wear a necklength ponytail.
