Style the hair and modify behavior

Consider the following to create a basic hair shape and style the hair:

lengthen or shorten hair ( Hair > Scale Hair Tool)
add more follicles or delete follicles, trim or extend hairs using the Paint Hair Tool (see Hair > Paint Hair Follicles and Paint hair follicles)
edit hair curves by bending, smoothing, curling, and straightening ( Edit hair curves)
use fields to style hair (see the Dynamics guide for information about field, Newton field, vortex field, and more)
use constraints to hold hair in position, such as to the head, or in clasps, ponytails and updos ( Set up hair constraints)
for special effects, assign a Paint Effects brush to hair ( Assign a Paint Effects brush to Hair)

To control how the hair style reacts to forces, like gravity, use the following:

field
hair system Dynamics attributes, such as Stiffness, Iterations, or even Turbulence for simulating blow drying hair
follicle Dynamics Overrides attributes, such as Stiffness, Length Flex and Damp
collisions ( Make hair collide)
collision constraints ( Work with collision hair constraints)
