I will tell you why we dont see more hair. Its one of the hardest things to model and is a task better done by a using a technique called subdivision or patch modelling. My method is Nurbs. I could make hair, but it would be harder for me and I am not sure that my hair would be as nice as if it were done with patch modeling. This is exactly why I am afraid of gloves - very hard to do these shapes with Nurbs. I could do extra pony tails and Bows and ribbons and some more addon hair such as spikes for AnimeDollKits hair.
