Unusual Circumstance

During my many games of officiating today I witnessed my wierdest event by far. A girl got her weave knocked out. I wanted to call something but I am unsure what the protocol is for such an infraction. I think I was in shock the player did get tangled up but no foul I wanted to call a foul but I couldn't think of what mechanic I would use and what he foul would be. I wonder???
