Just a random thought but have you tried using KCKT as a rinse out? My hair isn't particularly dry so I could probably use it as a rinse out once every couple weeks or so.
I've read a couple of your threads and I agree that you should go back to the basics.
Cowash and/or low poo, conditioner, leave-in (if necessary) and gel. I went through a period of several months a couple years ago where I used CG condtioners and low poo but didn't worry about my waves. Hair was definitely healthier and since I had no expectations about waves I didn't worry!
Plus when I went back to using stylers I got so many compliments about my new waves!
Coarse texture, normal-high porosity, normal elasticity (Komaza Care), very weak waves
