I may be defining this process as a four-step approach, however it's more like a three-step approach. The third and fourth steps are combined and are executed at the same time. Before we begin the process of drawing the hair, we need to be sure that the structure of the head is drawn in place. The structure of the head dictates the shape and flow of the hair and should be defined before we begin drawing the hair. Assuming that the structure of the head is in place, the first step is to define the outer contour or outline of the hair. This includes the lines that are formed as the hair overlaps the forehead, portions of the face, and the shoulders. In many cases, the hair lifts off of the cranium and may overlap much of the face. Of course, every head of hair is different and the contours that are drawn at this stage will be different for every subject.
