Part Chartreux cat, I think. Had some matted hair. Shaved area. Noticed what appears to be bad dandruff. Shampoo?

My part Chartreux, I think, had some matted hair on his back. I tried brushing them out but no luck, so, I happened to have an electric pet hair clipper, like cosmotologists use, and shaved the mats out. He has an extremely thick undercoat and I noticed he has so much dandruff it looks like he's been rolling in sand. Not sure which product would be best to use and not sure just how to bathe him as Chartreux are sometimes called the "waterproof" cat. Help.
