* Slightly tousled and sticking up in the back: This is the most common interpretation, and it looks natural and carefree.
* Spiky and chaotic: For a more dramatic look, you could make his hair stand up in sharp spikes.
* Wavy and unruly: This could be achieved with a hair product that adds texture and volume.
