sincerelly,
there is this other tool for hairs which i really recommand to anyone who want to make hairs and fur with a light weight impact on the performances comparing to this old one
[pro version if you wish the code source](Hair Designer Pro - Asset Store" style=“width:202px; height:260px; border:0px;)
or
[basic for users like me](Hair Designer - Asset Store” style="width:202px; height:260px; border:0px;)
with a cool and dynamic support on the forum
cheers
