I unwrap the scalp as flat as possible. So it will make easier once
you put the fur on it.

Once I've done that, I place the scalp inside the head and
scale it down in x,y,z axis.
Applied the fur on the scalp and experimenting with the settings.
Since I unwrap the scalp mesh, I will have extra attribute in U and V sample and
crank it up from 128 to 256 so that I can have more control when I use
direction paint tools attribute.

Here is the result.
I'm not really satisfied with the result because it's to bushy.

Side view.

Three quarter.
