mind if I ask you a favor? what did you do to rig the hair?? I model my character's hair from a mesh like it appears you did. I rigged the body just fine but for the hair I'm at a stand still...since it's poly hair I used this tutorial:
so even parented the hair to a chain of bones since that was the ONLY tutorial I could find on the subject.... but I don't believe it's forming the way it needs to...do I just have to pose EVERY hair bone just to get it to form the way I need it to move or does it suppose to move automatically when I move the main body rig.
for this one i didnt use any bones for the hair...i just put cloth to the hair mesh and weight the parts of the hair that will not move... i used bones on the hair of some of my models....here and here using this method here
