1. Load an image in Photoshop, particularly one with a fine/wavy hair line
2. Choose Filter/Extract or Ctrl + Alt + X to load the Extract Window.
3. Select the Highlighter Tool and paint around the edge of the hair line. Choose the Red Color Fill and a reasonable brush size of 4. Zoom in to capture those hard to see fly-away's,Shift + -(symbol) to Zoom out again.
4. Then use the Fill Tool to fill the areas you want to retain. Have the Fill color set to blue.
5. Presto! An easy extraction for such a complicated picture. I've added a neutral background color so you can see the contrast/difference.
