You'll be able to control thickness of the hair at both the root and tip, as well as bending, translating and twisting of the hair at root or tip, or anywhere along its length. You'll also have settings for kinkiness, not in the naughty way, at any point on the hair's length and with variable amplitude and height. Plus you can also dial-in clumpiness to aggregate hair into thicker groups of strands. The physics parameters of hair incorporate gravitational forces, spring strength and damping, air damping, bend resistance, root stiffness and the hair's tendency to return to it's original starting position after interacting with these forces.
