Actually, I'm afraid you are approaching this from the wrong angle. All the discussion above is from a technical perspective. You can spend a week painting hair in postwork and still not have a "wow". Someone else can equally, get a stunning image using a stock Koz hair and a few lights. What counts is inspiration, imagination, creativity and a good eye, whether in Poser, photography, paints or charcoal. I don't have a simple recipe for any of those.
