I'm mainly just curious. I've been thinking of trying to get out of my current restaurant job, and would like to own my own business someday. A hair cutting business seems like it would be a good idea. I mean, people will always need haircuts. How difficult is it to pass the courses, and to get certified? Would I be the only guy there? Who knows, it may be fun. I like to think outside of the box. I know it can be pretty expensive, too.
