For me, hair pulling is one of the, if not the most innately "feminine" physical aspects of a catfight and you'll definitely see some of it in every one of my stories. That said, it's damn hard to write a fight story solely centered around hair pulling and I can imagine it's only slightly less so to script a fight to be filmed. And while I did mention that hair pulling is a very feminine thing and will most likely happen in any competitive/real female fight that isn't between two highly trained women, I'd imagine that after "no eye gouging, no biting and no clawing", No hair pulling is probably the next requested rule (I know if I was doing something like that, I wouldn't want my golden locks littering the mat

. ). So I imagine finding women to compete where it is allowed is probably a little difficult.
