Some helpful tips for using an opponents hair ...
- Don't just grab the hair any old way. Slide your hands deep into their hair next to their scalp (preferably on the side of their head), then take a big handful of hair and twist to take out all the slack before you start working to manipulate their head. The twist makes the pull more painful.
- One advantage of the hair grip over a regular head control is that you can push as well as pull. Use pushes and pulls to control range and angles. The pushing action is also useful for ramming their head into things.
- Don't be static with your hair control. Constantly manipulating your opponent's posture and position and balance will make it hard for them to counter the grip. Your free hand can strike, defend, or set up grappling techniques. If they do start to get two hands on one to try clearing your grip, take the opportunity to secure a grip with your other hand.
- Don't rely on the pain factor. Treat the hair grip as if you are able to get a gi grip on their skull. If they react to the pain, that's icing on the cake.
If you have a training partner who is open-minded (or crazy) enough to try sparring with hair pulling allowed, it's an educational experience.
