I would try it with continuous AF (AF-C), on a single focus point. Then I would shoot at a very high frame rate, as much as possible.
It is very difficult to get sharp images under these circumstances, so the more you shoot, the more chance you will get the perfect one. Aim your focus point on the head/face, or eyes if you can as good as possible, and shoot many pictures by keeping the shutter pressed.
3D tracking does not seem a good option to me because it is not made for this situation. It is made for the situation where you want the background to stay the same, but your subject is moving. Changing the focus point manually is too slow, so there is a mode to do that for you. Here you don't need that, because the face (or head) seems to stay in the same place, and you can follow it with the camera if it does not. 3D tracking tends to focus on the object closest to the camera, so it would probably be fooled be the hair and focus on that in stead of the face.
