Does your hair get weighed down easily? Overconditioned?
Since your hair is fine, I'd go with the protein products. CJ Strengthening Beauticurls conditioner (but has glycerin high up on list) is good. I also really like the PT and DT by Curl Junkie.
I really like Oyin Hair Dew for a leave-in. Fairly light weight.
I see you already use the SS FHG. What about CJ Curl Queen for a gel? It's a medium weight gel that's less thick and more serum like.
Also, have you checked out Shea Moisture products? You could get these from Wal-Greens and Target. Depending on where you live, you could even snag some of the newer SM products.
