Shaggy fur even after dust bath

Hi, I’ve had my second chinchilla for few months now (I’ve been fostering him and only recently adopted). The whole time that I’ve been taking care of him he has had shaggy fur around his rump. His fur is quite dense, not as soft as my other guy. Even after a dust bath. He just has some longer pieces of fur that aren’t loose. I just want to make sure he’s healthy. Is this normal? Here are a few pictures.
Thanks! Any feedback is helpful. Attachment 22874Attachment 22875
