Yeah, I know I shouldn't do it. But I occasionally find myself doing it, nervousness is a b...h.
Anyway, I don't believe human teeth are sharper than scissors, do you?
Human teeth aren't as sharp as scissors but constant biting can damage the ends of your hair. I bit my hair once it was long enough to reach my mouth, but stopped after I noticed the ends were getting frizzy.
Most definitely, especially if it is someone else's hair!
I'd imagine that it would really fray the ends.
