I dont use PSP but I deal with the hair issue two ways - firstly I only go for the whisps that have a fair chance at surviving lol - I use the mask and zoom in a lot and draw teh selection rather than using teh edgfinder selection tools, I use a feather to try and get rid of the edges that I dont want and then I use a clone brush (using the hair as teh sample area) to cover those edges so teh whisps are a bit thicker but not as jaggy
HTH
