This is probably the most powerful shader and rendering settings i have ever developed.
This is a render showing 10,000 nurbs curves, with a thickness of 0.1mm (same as human hair!) with an applied hair shader that i made. You would expect this type of model to crash any pc. Well i was able to get this baby to render in under a minute by using instancing even in best quality. the hair interacts with light so it changes colour in different brightnesses. Well tell me what you think of my shader.
