I'm going to go a little against the grain here and say that if you have a tired, old, hairstyle (like me!) and want to try something new and cute, go for it! If you state who you are, then I think they will be pleasantly surprised at your beautiful new style, as long as it's something positive.

I don't see why going back to your natural hair color would be so bad. It might throw them off at first if your senior portraits had you in bleach blonde hair and you have raven black hair, but it IS the real you.
