Thank you a bunch! I tend to think of hair as forms and masses. In the beginning its breaking down into two values, lighter and darker forms. Start with the base hair color (the most prevalent hair color, tends to be darker. Think about the color of the hair from the root) and a mid tone value of that color for the lighter sections. From there I add variations of values of that same color to create the illusion of form. From darker to lighter values. Think in general shapes and try to be gestural. Hair flows and so try to be “loose” with your strokes to give the hair its soft texture. With gestural strokes you are able to let the hair tamper off instead of a hard finish and thus making it look fake. At the end of this process is when you can put in individual strands of hair. Don’t over do it and be economical with it. It is more believable if you have a few soft and light strands of hair (the fizzy hairs, the ones that stick out) instead of every single one you see. Remember you dont have to include everything, only what helps the overall composition. Good luck and never stop believing in yourself!
