If you’ve struggled with retouching fly-away hair in Photoshop, this tutorial from Daniel Sone at Tuts+ may help. Daniel demonstrates three techniques using:

1. Clone Stamp tool
2. Healing Brush tool
3. Surface Blur

Surface Blur is a tool that “considers something an ‘edge’ when there is a significant change in color and/or contrast. So, things like skin, clothing, and other fine details will be smoothed, but not the edge of someone’s face — or the main mass of hair.”
