The biggest problem with the hair out there now is that it's like working with shellac and winds up looking that way. To get your hair to flow properly, you're gonna need a lot of joints, clearly, and to get the right sense of density, it's gonna need multiple layers. In all honesty, I don't think 25 joints per layer is too extreme, not if you want it to really flow. It might be a pain to pose, but the reality factor would be right up there when you're done.
