A bone with intertia.

So I’m making a game character lately, and I’d like to have a bone or two for the hair (simple 20’s -like bob cut), to move around when she moves in the BGE. Anyone know of a way to make the hair move on it’s own and follow the motion of the head? I’d have to constrain it so it doesn’t go wild of course.

Or should this been done in the physics panel? I’d like to be able to bake it to the hair bones just in case.

I’d like this to happen on it’s own rather then animate the hair by hand.

EDIT:
Dang, made a typo in the topic - can anyone change that?
