Hair tutorial - Ponytail and fringe.
This tutorial is for Photoshop 5.0, but works in other versions of Photoshop as well.
 
1. Pick the middle colour and draw the shape of the hair on a new layer. When doing fringes a tip is to make it a bit uneaven instead of strait accross the forehead. 2. Select the area you've just drawn and create a new layer. 3. Pick the darkest of the three colours, and go to Edit > Stroke to make the outline. The settings should be Width: 1 pixel - Location: Center - Opacity: 100% - Mode: Normal.
     
4 . Create another layer, place it under the outline. Choose the middle colour again and make a big field that cover the whole hair-area. This is because if you smudge outside a colourfilled area the edges and colours get messed up. 5. Take the darkest colour and draw strands using the Paintbrush tool. 6. Pick the lightest of the colours and draw the light strands also by using the Paintbrush tool. If you want you can smudge to soften it up a bit, but isn't always necessary.
     
7. Select the first hair layer (step 1). 8. Delete the areas outside the hair. 9. Change the outline layer to Opacity: 70%. Merge the outline layer with the layer you've drawn the dark and light strands on. (It's a good idea to keep a copy of the two layers in case you'd wanna go back and change something.)
     
10. Use the Dodge tool to dodge on the hair where you'd like it to be highlighted, for example on the fringe and ponytail. Don't over do it. Highlights on 20% is a good Exposure option. 11. Create a new layer under the layer you've just dodged on. Pick the middle colour from the palette and, by using the paintbrush tool, draw just close to the edges of the hair to make the hair blend better with the skin. Adding a strand here and there is a nice touch as well, especially on the ponytail.
