Exercise 1: A very hairy way to draw hair is by only using dashes. Draw some hairstyles using only dashes.
It is, of course, impossible to draw as many dashes as there are hairs growing on someone’s head. You get more possibilities if you start with the shape/contour of the hair like a kind of soft hat over the head. Even a clear contour can then be enough, as in the following drawing of a woman with curly hair.
Once you can picture the shape or contour of the hair, you can look at how the hair falls or how it is styled within that area. This can be done in combination with shading. In the following example, it has become a play of light and shadow, without a clear contour like in the previous drawing.
Exercise 2: Copy a number of the following hairstyles or make variations on them. Start each time with an egg-shaped head (with eye level approximately halfway). You can omit or change the faces.
