You'll need:
* Item idea
* The base
* Adobe photoshop, tablet / any tool you use
* Patience and creativity
Step 1
Open up your base image. It's good if you have a version of eyes on it since it can help with the placement of the fringe/bangs.
Make sure it is on a separate layer from the background! Then bring in your grey scale palette.

Step 2
Now, if you have a reference image, paste it in there, preferably below the base layer. You dont have to stick to the reference image 100%, be creative and alter some parts if you feel like it. In this tutorial, I'll be inventing my own long wavy hairstyle.
Sketch the main shape of the hair on a new layer which you named "sketch" or "scribble" or any other witty thing you came up with. Use a color that will show on the base. Use a 1 px brush for this.

Step 3
To begin blocking in the hair, take the pencil tool, 1 px. Make a new layer and name it to your liking. Then start tracing the edges of the sketch, dont hesitate to rethink some parts. Once you've traced the outlines, fill the area with the paint bucket tool.

Step 4
Make a new layer for shading. Bring the sketch layer above the 'HAIRBASE' layer.
On the new layer you just made, mark down the most important lines that will guide you through the shading. Use the second darkest shade of grey from the palette.
To keep from going over the lines, select the 'hairbase' area by clicking on the thumbnail of the layer while holding down 'ctrl'.

Step 5
After you're done, hide the sketch layer again.

Step 6
Drag the shading layer to the hairbase layer and merge the two.
Lock the layer!

Step 7
Add in more shadows. Start bringing out the most important details.

Step 8
Select a shade between the second darkest and the main color.

Step 9
With the selected color, add in more detailed shadows. Fix any details you want to fix.

Step 10
Add depth to the hair with the darkest color. Dont go overboard with it!

Step 11
Time for highlights. Select the second lightest color and start highlighting the hair. Not much is needed since the shadows have made it look quite detailed already. Make it kind of soft.

Step 12
If you want, take the lightest color and add in more detailed highlights.

Step 13
Clean up by selecting the hairbase layers image area and reversing the selection. ( hold 'crtl', click on the thumbnail of the hairbase layer, inverse selections and press 'delete' or 'cut')

Step 14
Merge~

Step 15
Sometimes, although all the hard work, the hair wont looks shiny enough.
Use 'Levels' to increase the contrast between the darkest and the lightest color. This step is entirely optional.

Step 16
And if you find, that the highlights and shadows need some smoothing out, use the smudge tool, 2 - 3 px in size. Dont make it completely blur!

Step 17
You're ready to add color to the hair!
