A hair-related course of study

I just wanted to say that it sounds like a very interesting subject. Good luck.> Since visiting many hair sites here, I have a great> desire to learn more about hair. I am thinking of> taking up a long-distance correspondence course but> not anything related to hair cutting or styling.> Rather, (this sounds weird) I am interested in the> chemical contents of hair-care products and also the> way hair grows and its maintenance. I can't put a> finger on something specific, but I do know I don't> want to be a hairdresser although I am very interested> in other aspects of hair and possibly the> scientific/biological aspect of it, maybe a profession> as a trichologist??> Could anybody tell me if they know of any hair-related> correspondance learning courses which does not end> into a professional haircutter?> Thanks!
