To answer your question: It's to be used with Michael 4, so the figure is no problem. It's an expansion set, but it doesn't list a main set. Apparently, it can only be used in DS 4.8 or higher, and that's because of Iray shaders. I did check the many of the hairs DAZ has on sale for M4. They also seem usable in Poser, although if it's a Genesis hair, you might need the DSON Importer. Hope that helps.
