Not sure if they're protein-free, but here are my recs
Herbal Essences Body Envy (in the orange tube) - my current favorite. Holds well, and provides shine.
Herbal Essences Set Me Up (turquoise tube) - 2nd choice. Good curl formation & hold, but quite as much as with BE.
Herbal Essences Totally Twisted (purple tube) - a tie for 2nd choice. I find I need to use more of this than the previous to in order to get sufficient hold, but still an all-around decent product.
