"in Monsters Inc, they created what were called Master Hairs, that were used to direct the motion of all of them - you would have something like 1000 strands assigned to a single Master Hair, and they would all move more or less in concert." Don't know the specifics, but apparently Lightwave 7 has a similar capability. I'm dubious about it's abitity to do human hair, though.
