Have you ever considered going to cosmetology school? Many of us at wigs.com
are licensed and it's the best way to learn how to cut and style hair, which will naturally translate to wigs. You'll want to be licensed in order to work on humans, as a wig stylist many times will be tailoring a wig to suit the person, and the natural haircut they have. If, for instance, they are purchasing a hair topper then they will need it cut to blend in with the rest of the hair that will show underneath.
A side note: Beauty school is a TON of fun! And after that, find a local wig salon and apply to work there!
