Hi Tony,

I feel your pain, but when working with a plain toned background, such as a green / blue screen, the best method I use is the extract tool which comes with the Photoshop extended software. It allows you to paint around and over, just the edge of the whole of your subject including fine wispy hair. Then, by pasting with the paint bucket from extract, you fill the centre area of the image you want to keep. By pressing OK, you’ll come up with a pretty good version of just your image, with all the fine detail of hair, with your transparent background.

You can fine tune any areas at the edge, where the technique may have eaten away a little bit of edge transparency by using the history brush, pasting info back.

try it. I’m sure it will help

regards
