Ok, I had to draw a little bit of hair, but actually it wasn't that bad. The part over his forehead was done with a lot of dark and a few lighter strokes of the pencil versus the front.

The hair that sticks out on his right side was done using the kneadable eraser for the brighter parts and the HB mecanical pencil (0.5mm) for the finer hair.

The beard at this point consists of a few darker and lighter smudges.
