3D sculpt of the actor Jim Parsons.
I made this 3D model in ZBrush and rendered it in 3ds MAX. The hair is also 3d sculpted and not done with plugins. Therefore it could not look 100% photo-realistic. You can see untextured model in the following images.
As I am not satisfied with current 3D hair solutions on the market, usage workflow, stability and output, so I did not invest too much time researching plugins. What was fun is researching how the hair is represented in traditional sculpture, and taking different techniques into realizing it digitally.

I played a bit more with the model, and tried to make it into a caricature. I am not very satisfied with results but here it is anyway.
