Hmm... Well, if you can find it in a drugstore (many people have found it there, but I was unable to in my area), Renpure Organics has a new keratin condish. It's actually called "straightening", but it doesn't cause any curl loss, so don't worry!
Shea Moisture has a decent amount of protein.
I was about to suggest GVP Kpac or Ion reconstructor, but those are both at Sally's - duh! Tho Sally's website of course can deliver to you! Shipping is $6, I think.
My hair LOVES protein, and those are the 4 I use. Only the SM or the Renpure are at the stores. :/
Have you tried the gelatin PT?? It's amazing and WAAAAY cheap!
