It seems to me that the idea behind the hair room is fundamentally flawed. Strand based hair, I mean. One of the first things you learn is a figure drawing class is don't try to draw every strand. Do it as locks. And in you add in that the average human has what, 60,000 strands of hair on their head? You're either going to have a lot of polygons, or a thin-looking hairstyle, or the strands are going to look thick and unnatural.

I would love to see a form of lock-based hair, where instead of individual strands, you grow transmapped planes and style those.
