For dynamic hair, you need to set the collision detection checkmark on the body parts that the hair should collide with (head, neck, chest, collars, maybe shoulders if it's long hair). You also should start from a zero pose, that usuually works best. You don't have to, though; you can also start with the end pose and use the styling tools to make sure no hairs intersect with the head/neck/shoulders/etc. A hair simulation always has exactly as many frames as the animation toolbar tells you. Unlike cloth simulation you can't change that. You also can't set the number of drape frames or disable draping. A problem with collision detection is that it's SLOW! Especially on a heavy poly figure like V3. Hair calculations can easily take hours, even on a fast machine. kirwyn has developed a nice trick: he made a very low-poly proxy figure, only a few dozen polygons, more or less in Vicky shape. No details for ears, eyes, lips and so on. The Jessi and V3 varieties are in 'rosity freestuff, and they come with a tutorial. I highly recommend them. Caveat: dynamic hair usually works best in animations. If you want to render stills with good looking dynamic hair, it's better NOT to do a simulation. Instead, pose your character, apply the dynamic hair prop, and use the styling tools in the Hair Room to move and twist the strands. It's better to keep the vertices per hair count fairly low, and use the polygon smoothing render options to remove the kinks in the hair. This goes for both stills and animations. For animations, you'd probably want to have a fairly large root width, so that the total number of hairs can be kept fairly low. For stills, reduce root width to 0.6 and tip width to 0.2, and increase the number of hairs. Dynamic hair is an infamous resource hog. On my main machine I have no problem rendering multiple Millenium 3 figs with clothing and transmapped hair, with high quality dynamic hair I get restricted to a single nude figure and a background image... But the results can be pretty nice (see link).
