I don't know if this is the same thing....but in Poser circles at least, some people have experimented by taking prop hair and its groups and "clothifying" it, then running cloth dynamics simulation. The computing power to control perhaps 10 groups on prop hair vs 20,000 strands of dynamic hair.....you can see the thinking. I have not tried this yet. How well does cloth dynamics work in Carrara? ::::: Opera :::::
