This is the best I could do.

These are the steps I took in my method;

Import image to Photoshop. In the layer palette add a plain black background so that the imported image layer is just above it. Selecting the image make a copy layer of it placed on top of the original image. In the menu chose Image->Adjustments->Brightness/Contrast and slide contrast to +100. Do this three times. Then again in the menu chose Image->Adjustments->Threshold and click “OK”. You now have reduced the image to black/white. This will be used as a mask to trap light areas around the hair. But we must first get rid of the none-essential areas that we don’t want taken out such as the face, neck and sweater. We do this by using a hard brush to fill those areas with solid black. Once we have all the light areas around the hair we then need to convert the layer to an alpha mask in the channel palette by selecting the Red channel and making a copy of it. Using the magic wand we select the black area behind her shoulder and then using Ctrl+Shift+ click on alpha channel we add the alpha mask to the selection. We invert the selection pressing Ctrl+Shift+I and use this to lift the entire person from the background. This will get most of the highlight from the hair out but leaves some artifact colors. We select a dark color from the subject’s hair and using a small brush we paint over the off-colored artifacts. We then set blur at 25% and using a small brush we finely blur the outskirts around the hair. Finally, we flatten our image.
