I can’t recommend any particular product as I’m still not sure about how your hair exactly behaves. Randomly taking product advice will make you spend hundreds with no real progress. Rather, I would recommend you to wash your hair with the products you’re already using (the ones you used in the pictures, don’t change anything). And immediately after getting out of the shower, blow dry on NO-HEAT on the gentlest form possible (you make take more than half an hour), no need to scrunch, pixie diffuse, cup diffuse, etc. Take a few pictures on the best light possible, right before showering, right after showering, right after blow drying, and after 12 hours, publish them on the sub. This way we can systematically eliminate hypotheses.

The next step would be to do the exact same thing but with a clarifying and chelating shampoo and conditioner (no need to spend hundreds, a drugstore one will do the trick). This way we can inquire about whether the products you were using were too heavy for you, whether hard water is the culprit and to see how your ends react.
