I have tried working with Quarkers Grace Lion Hair (I love that hair!) I emailed PhilC about it and he told me to turn it into a prop first. I did and tried it but all of the pieces flew off. It has to be all one piece for it to work and I don't know anything about modeling to be able to weld all those pieces to the base model. I have been learning wings3d so that I can fix it. I haven't tried it yet with a more simple hair model.
