You can try any of the suave naturals (I like the coconut or the clarifying) conditioners for co-washing, and have used the coconut as a LI), or the vo5 Shea cashmere is awesome as a RO or LI.

I'm not sure what conditioners have low humectants, tho... :/

A lot of people like Yes to... Line, and I love Shea Moisture's line. Idk if that helps, but some things to try, I guess!
