Just hair that I'm more used to. In the United States, the "normal" hair that you've seen is the common hair you generally see on women on the street, in movies, on TV, on shampoo commercials, etc. Also, as much as I like the very long hair stuff here, it is nice to shake things up a bit with some variety and post hair of more normal length so things don't get boring or too repetitive. And also to show that more "normal" hair is just as silky, soft, shiny, sexy, capable of hairjobs and buns and ponytails, etc. as hair that is extremely long.
