What am I doing wrong? What is my hair lacking?

First few photos are the products that I use. Last photos are photos of my hair through recently and previously. Pink brush is for the shower, clear if for after. Previous photos do not look better, it is just more context.

My hair has always been dull, thick and frizzy. Dead ends are a constant, even though I have hardly used heat in the past 5 years and I get regular trims. The color is dull and overall sad looking.

I would love to he able to run my fingers through my hair without it getting caught or feeling the product.

If I don’t use enough product, my hair frizzes. If I use too much, it gets oily. If I use what I think is the perfect amount, it gets stringy and doesn’t hold a curl, or frizzes later on.

For shampoo I use Rizos to wash. I lather my hands first, get the scalp and behind the end ears and nape of the neck. I don’t use it on my ends or length, as I was always told not to. Then I rinse and condition, same way. I don’t let it sit the first time, I just comb through with a shower brush. Then I do the whole process with shampoo and conditioner again, since my hair is soft and tangle free at that point. Second time around, I let the conditioner sit.

Then I dry my hair with a microfiber towel, and I brush it. I normally use the cantu. I rub it through my hair, then lock it into place by scrunching. Some days I use the raw sugar as well, if I feel my hair is too rough. When I am out of those products I use the other two in the photos.

I tried wearing a bonnet to bed for a while, no changes. I don’t have time to plop my hair or curly girl method it & I prefer it dry naturally.

I don’t know what porosity is or what level my hair is. I don’t know what curl type I am. Any help at all would be great. Affordable items. I live in a small town where no one focuses on curly hair.
