The specified polygon and vertex count is for the emitter object NOT the hair itself. Two particle systems have been used to make the hair model. The first is the locs, the second the growth
Here are the details about the particle systems:
Locs:
100 Hairs
50 Interpolated Children
35 Segments
9 Steps (B Spline)
1 Vertex Group
Growth:
3000 Hairs
10 Simple Children
5 Segments
3 Steps
1 Vertex Group
There are two emitters for the hair, each having two particle systems attached. Two halves of a scalp making up one singular head of hair
