Don't use coconut oil neat for everyday, use it regularly as a pre-wash on dry hair, ideally overnight before wash day, or as an ingredient within a conditioner. You could even use it to make a variation on the DIY Ecostyler custard. Curl Keeper and KCCC are indeed lovely products in the right weather conditions.
Maybe read the lengthy thread on the Komaza Care analysis and see if it gives you the sort of information that would be of use to you or not. It's incredibly detailed, it would be pretty pricey if all you got out of it was the hair properties!
