try low pooing, it won't dry out your hair. you can even low poo a couple of days in a row, should be fine. then leave a good leave in in, i like curl junkie conditioners. you mentioed cj bcli, that should be good.

if you are not washing/cowashing every day, then it might take a bit to get it back in balance.
