HAIR FRIZZ

[ Hair without (left) and with (right) frizz ]

To make hair appearance realistic frizz is usually added. Because in real world no hair is absolutely straight and external forces (such as moisture) cause it to deform, a special treatment for hair is required to achieve this effect. Standard Max noise modifier can be added to make hair appear messy, however frizz modifier messes up hair strands along their length without changing their length. Often hair frizz can be combined with standard noise and curling to achieve the final result.
