Nah, it's good. As the commenter above said, not everyone's hair is affected strongly by the sun. I spent entire summers surfing as a teenager, and, AT BEST, I'd a couple of lighter streaks near my temples. Now spending much time in a chlorinated pool, otoh, would bleach my hair quite a bit. Depends on the person, I guess. I like Kyuubi's reddish brown, though. It seems fitting.
