How can I take care of my scalp without brushing out my curls?

I have 3b curls and the only time I "brush" my hair is in the shower, fingercombing, with a lot of conditioner. But I have noticed that I tend to get a large build up of dead skin on my scalp that usually brushing would get rid of. Is there a way to keep my scalp healthy without having to brush my hair so that I can keep my curls popping?
