Thanks so much for the advice!
I've never been that into my hair or learning more about it, I just sort of hope for the best and let it do its thing.
The reason I like to use a line is because, in my mind, the products are designed to work with each other and I do not have the time, money, or patience to try every thing when one doesn't work.
My hairstylist brother recommended Rusk which I know nothing about, and seems to be of quality, but I am not sure about how it will work with curls. (his formerly naturally curly hair is magically straight all the time. I don't know what kind of magic did that.)
