You most definitely have your own choice as to how you wear your hair!! As my dearest auntie puts it: "Hair is a renewable resource". I, like Jess, am only sixteen, but I'm currently entertaining visions of having long white hair when I'm an old lady, done up in a braid. I'll probably change my mind when I actually start going gray, but who knows, right? Do whatever makes YOU feel the most comfortable, and let society (and "friends") say what they will.
