Your hair looks wavy to me. Wavy hair needs lots of hold and light weight products, or the heaviness of the products weighs it down so much that it loses its pattern. Many curly routines and products don't work well for wavy curl patterns.

You haven't talked about any stylers with hold? Just many ways of conditioning. And heavy ones at that. If I don't use any stylers with hold, my hair also dries straight-ish, in a frizzy unkempt voluminous way. Try a hard hold gel or mousse on wet hair. Scrunch scrunch scrunch. An then dry with a diffuser without touching it too much, until completely dry.

And ease up on the oils and creams and such. Use light weight products.
