After a lot of experimenting with Hair Salon I concluded it is in need of much deeper documentation. The current docs give some examples of usage but miss an explanation of the concepts (like when use hair or fur mode etc) and most buttons/controls aren't explained at all.
One gets to good results after playing around but many things are guesswork: How many hairs do I get per guide? What does max hair do? How does colouring work? Can I change the material properties of hair (i.e. to make it more shiny)? What advantage has Hair over Fur?
I plan to write a tutorial on my findings but many things I simply can't answer because of the guessing
