Your hair sounds a bit like mine as far as curl. I had been on CG for almost two months when I had my hightlights done and my hair came through it very well.
I love the GVP line from Sally's. I specifically co-wash using their Paul Mitchell The Detangler and ocassionally the Paul Mitchell Tea Tree Conditioner copies. I use their version of Matrix Conditioning Balm as a leave in. Then I use Volumax Volumizing Gel, plop for 20-30min, clip like chicpower's tutorial and let air dry (sometimes diffuse a bit). SOTC with my hands or a bit of Bioterra Curl Cream and go.
You may need some deep treatments too. I like the Lustrasilk products from Sally's (sometimes use the CB to deep treat too). You can also try protein (GVP has their version of the Joico K-Pak that's good), but you need to follow up with a moisturizing deep treatment.
As you can see I love Sally's for products.
Best of luck and hang in there. You are doing something wonderful for your hair!!!
