By default, hair is created on the surface with equal distance. If you enable the random placement option, the hair placement will be chaotic.
Noise is needed to curve the hair and give it a wavy look.
To correctly display the frequency and amplitude of the wave, you need to increase the number of hair segments
Frequency - number of waves per unit length.
Additional small waves that are superimposed on top of the main ones
Сhange of weight between frequency waves and octave waves
Сhanges the noise intensity along the length of the hair.
Сreates a range around the main Frequency parameter.
Frequency + (- Min), Frequency + Max.
You can control the amount of low frequency hair or high frequency hair with ramp
You can vary the noise level on different hair
You can change the amount of hair with strong distortion and low distortion
