Some great lines are Curl Junkie, Spiral Solutions (when she's up and running again), Donna Marie, Marie Dean, Komaza, Kinky Curly--just to name a few.
My hair is fine and not very dense as a result of age, thyroid and medication issues. I use small amounts of the richer products with no problems. My hair isn't dry, so I don't need to DT. I do at least one PT a week--CJ Repair Me and SS Protein Repair Treatment are both very moisturizing. As long as I'm using lots of protein, and don't overdo the rich products, I don't have issues with my hair being weighted down. My hair is low porosity, so it takes it a while to absorb the products. My hair actually gets better as the day goes on.
