I like CO washes, but they can be kinda finicky imo. I believe that co washes don't clean your hair much if at all, but they certainly can moisturize. The key seems to be to keep products that are prone to build up ( cones, heavy pomades and butters, etc...) to a minimum and to make sure you to clean your hair with something other than a CO wash when the occasion arises ( like using an acv rinse, baking soda, or shampoo).
If you follow those general guidelines and of course not use heat you'll probably be okay, unless your hair just doesn't like the manipulation or need the moisture.
Another alternative is to just mix a few dabs of shampoo and conditioner in a bottle of water and to wash with that and condition afterwards if needed. That gets the hair cleaner without drying it out, good for inbetween co washes or shampoos. HTHS.
