I just meassured a fallen strand, it came in at 15 inches, I think it was one of the shorter ones.
no hats, though if it is winter I will wear a tuque.
If I go outside I usually wear a hood to keep my hair back, and because it is usually pretty greasy. I wear it in an elastic sometimes when I am in my room, but I am too afraid to near other people. Also when I am alone in my room I turn my shirts into either a ninja thing, or into a dew rag/ pirate looking thing, you should do it too, it is fun.
also I haven't used any soap products on it in like 6-8 months(?), water is fine.
