This is Juno Hair by Biscuits. Straight out of the library, I spun none of its morph dials. I did not subdivide the hair model. V4 with Lana Elite skin maps from Daz. SSS by EZskin.

The render required 4 hrs 18 minutes with Firefly. Poser Pro 11 on Windows PC Core i5 8400 8GB RAM, no video card.

I applied Karina's SSS shader to the hair with no changes (except plugging in the two image maps.) Normals forward. GC 1.0 on all B-W hair and body transmaps, 2.2 on the color maps. You can see my render settings below.

If anything, I think it is "too" crisp. Makes the hair look dry. I didn't try to fix that (or any other issue) in postprocessing. Perhaps more specular is needed.

It's quite a balancing act to get the lighting of the hair to match the lighting of the skin. If so inclined, I think my next approach would be to export out of Poser .exr and open in a graphics app that can control tone mapping HDR.
