This is an ugly image. Never mind. There are a couple of puzzling features.

I used here Janet's hair maps, uv-scaled x500 along u, and on fairly wide 
ribbons (default Poseray values). Other values might give better results of 
course.

Puzzling feature 1: The background shines through the figure! Not only the 
hair but also the underlying skin. I had noticed this in a much earlier 
experiment but forgot about it.

Puzzling feature 2: the transparency at the hair tips casts shadows on the 
underlying skin.

Additional comment: I am still not sure about the usefulness of the ribbon 
roots. They are detached from the hair proper. Why not grow the hair 
directly from the line origin?

Rendered with POV-Ray 3.7 on dual core machine. Render took about 25 
minutes. No radiosity.
