Oh, dear. Well, for what it's worth -- very little, because I haven't set aside the time to deal with the videos yet, because video tutorials make me crazy -- what I remember hearing in the forum when this first came out was that in general, hair isn't going to work because it typically has both a skullcap and the hair cards/strands, and the hair isn't welded to the skullcap. So what winds up happening is that dForce can't really tell that the hair is supposed to be stuck to the skullcap, and then the hair falls off.
I also remember them saying that it works best when the figure has nothing more than the dynamic clothing on them -- ideally, no shoes, jewelry, hair, whatever. Which seems, in part, to be true, in my very limited experiments.
