Hair Tutorial (by Tafkah)
In this tutorial, you will learn the method involved in building hair from scratch. Forget about your clippers, put away your scissors (don't run with them either). Chia Pets need not apply. This tutorial is simply about drawing hair (think Don King).
Page 1: Preparing your image
Adjust and edit your image up until the point where you will add the hair. This prevents having to match lighting and color later.
Create a new layer and name it Colors. Choose the color of your hair and pick 4-5 tones going from the darkest to the lightest. Use a regular hard brush to paint samples of them on this layer. This will just make it easier to sample from them later.
