JB: This isn't bad at all. You'll find amazing results with the "smudge tool" in Photoshop. It's the hand-with-index-finger-pointing-downward icon. On a separate layer, select a fairly small brush--maybe 9 pixels or so (depending on the size of the image)-- and an opacity of about 70 or 80 percent, and smooth-out/blend the lighter hairs into the darker, and vice versa. Experiment with larger brushes and different opacities. Good luck...
