I prepared a model example. I usually use three layers of hair together. The first layer called "Pubic_Ground" contains the shortest hair. The second layer called "Pubic_Main" contains a hair of medium length. The third layer called "Pubic_Center" has the longest hair.

Length and density of hair is determined by the value of the parameters "Kink Strength", "Kink Scale" and "Verts per hair".

For material of hair I use 50% transparency. The resulting effect depends greatly on the scene lighting. In this case, I used a simple raytracing.

Especially, I used a huge pubic hair ;o)
