Really the big problem with the recently released Daz hair is the textures. After all, Koz did some textures for the old P4 hair, and now it looks great. If you've got P5, try this trick. First, link the reflection to the texture, and the reflection strength to the transmap. Set the color of the reflection down (grey it up). You may want to turn the reflection value down some too. Second, a lot of these new hair don't have a bumpmap. So link the bump channel to the texture, and set it between .1 and .4 or so. Third, link the specular color to the texture and set to white. Play with the highlight size some, and link it to the transmap also. Real hair has a sheen, and an almost metalic look when cared for. This method can really help. But the best thing is to hope that Koz makes textures for them. No one does it better.
