umm... parenting things to the follicles sounds like a bad idea - I'm pretty surprised it let you get away with it (if you're talking about the hair curves, anyways).
Probably the only thing I would have parented would have been the nurbs skull cap... And I would have either parented it directly into the skeleton heirarchy at the proper joint, or parent constrained it to said joint.
Mind, I have no great experience with charachter stuff, but a lot of the rigging work I've done for machines falls into the general heirachy category this does.
