Like glamazon said, it depends on your hair. Every natural's hair is different.
You'll definitely need a moisturizer. Stay away from drying shampoos - get a moisturizing one or do a low/no-poo regimen. You probably won't need a protein deep conditioner as much as while relaxed. I don't use one. Co-washing isn't necessary for some (including me), but you can try it. Denman brush - I don't use one, but some do.
As for product names, just go out and try what you think may work. I tend to hear that more natural products work best on 4a/4b, so you may want to go that route. Qhemet, Oyin, etc.
