Thanks to technology, art savvy users can visually edit pictures with the click of a button. This video tutorial demonstrates how to color hair in Adobe Photoshop CS. In Quick Mask Mode, color over the hair area with a fairly large brush. Under Filter, select the Blur category and apply a Gaussian Blur to soften the edges of the mask. Revert back to Standard mode where the mask will appear as a selection, and under Select, choose the Inverse option. Finally, adjust the hue and saturation to subtly change the appearance of the hair.
