Question about hair

Hey! I have this operetta roller maze doll, which is one of my favorite dolls I own! I also have one of her fashion packs which I’ve been thinking about putting her in. I was just wondering if anyone’s cleaned her hair before and if I should? I like how her hair looks but I don’t like how it feels, and if I’m putting her in a different outfit I’d probably want her hair to look different. I’m just not sure what to do.
