Frizz Modifier
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.
Hair with frizz and noise combined together
You also have the control over 'outliers': these are rebel hair that stick out the most. Outliers (or wild hair) are usually composed of few strands that you see sticking out of dense hair in real life. These add more spice to hair simulation.

Allows defining the frizz effect along the length of the strands - Scale
The granularity of the frizz effect - Seed
Random seed to use when generating frizz - Frizz Map and Guide Channel
