How to create Photoshop hair brushes

In this Adobe Photoshop tutorial Bert magically creates hair and fur from scratch with the pen tool and brush engine.
First, Bert creates long flowing hair using the pen tool (for the shape of the strands), define brush preset option (to create a unique brush stroke), the brush engine (to adjust the custom brush) and stroke effect (to add effect).

Similarly, Bert makes fur by creating a custom brush stroke with the pen tool, paths, define brush present, brush engine (adjusting scatter and count) and colorize effect.
