Here experimenting with some strand based hair. The hair I modeled in Houdini, with some wind blowing.
The highlight goes to the rendering in Poser using Cycles PrincipledHairBsdf, which offers realistic control over melanin.
Hair mesh stats: 6,017,880 points. It takes a little while to load but as it does not use transparency or image textures of any kind it renders reasonably fast considering the result (I believe this one was around 1 minute).
LaFemme's shape is: Loni Face/FBM 1.0, LaFemme Body_Curvy 0.5.
Rendered in Poser 13 Superfly, preset optix high, 1920x1080.
La Femme Pro 2, Premiere Dress for La Femme 2 (RPublishing, AfroditeOhki), Loni (ShvrDavid), wooden_motel_4k (Sergej Majboroda).
