I bought Nirveys' Hairkit 3 last week. I just finished my first attempt. There are two ways to use the hairkit. The first are the layers described by Engel47. The second is to paint the hair on using the brushes. This is a more elaborate process. It requires painting the hair in layers, modifying color and position, then you can use the dodge/burn tool to apply hilites etc. I've found the kit fun to use. Keep experimenting. Bill
