I use PhilC's hair designer to ceate a fitted skullcap. Then I take it into Blender and edit the hairline. I usually need to cut away a few rows of polys from the forehead.  I also group it in Blender, though you can do that in Poser. I like to subdivide the polys around the hairline and along the parting, usually around double density, it depends on how I intend the hair to fall eventually. I use centimeters for my Poser units so it is difficult to compare density figures, I am not sure how they work anyway. For me it is still trial and error. I have found that if the hair is too dense, it starts to look like plastic.

I don't like the hair exactly the same colour all over, so I often plug in a texture or a shader node to create some variation. The wood node is surprisingly useful to make highlights. Granite works. Or you can use a stone or fur texture. I used to use Adorana's hair colours a lot but now I prefer to play around and make my own.
