Eyelashes with hair as in Maya's Xgen

From minute 6:00 you can see how it’s only using a few guide hairs but I cant get that same interpolation in blender, which ironically wirks better when using simple instead of interpolated as children.

Looks like interpolated needs weight paint to work, a little bit better, looks like that’s the key to improve eyelashes… Maybe refining the weight will help as well… Maybe some other setting as well?
