I would highly recommend Curl Junkie Deep Fix or Curl Rehab as a dc. Repair Me is a good dc too that has protein in it.

Kinky Curly Knot Today, Curl Junkie Aloe Fix Gel are good gels. EcoStyler also makes awesome gels. I like the olive oil one the best. But, they're all pretty good. They're also cheaper and easier to find than KCKT and CJAFG.

Sorry, I can't really give any advice on protein treatments because I don't use them. If I need a protein boost, I just use a dc that has protein in it.
