Try turning off the specular node in the mat room and plugging the antioscopic node into alt specualar and play around with that.  I also find a contrast brush in post work gives hair a little more vividness.

If you want the hair to be finer, you'll probably have to make new texture maps at a new resolution (I think poser supports up to 4096x4096 maps).

WARK!
