Is this the PSD layers you are talking about? In the readme for the hair kit it says "HOW TO APPLY: Save an image in a format that supports layers (i.e. Poser in the PSD format). Open your image in any graphics program. Choose a layer or more of hair. Copy and paste.Rotate, mirror, alter colors, flip,cut, do whatever you think would look good on your images, cut parts of the hair and add them under the previous layers or above. Your imagination is the limit. Open your poser image - open the hair PSD, copy the hair paste to the image of the figure, then resize it as required - alter the hue and saturation move it where you want it, etc, - whatever you want - I have both kits and get good results from them.
