I don't have the same type of hair that you do but when I was first starting out trying CG I had a hard time with my scalp too.

I think you may like Jessicurls Hair Cleansing Cream. It's a nice gentle cleanser (sulfate free, not real sudsy) that really keeps my scalp clean. Her Aloeba is a nice light conditioner also. And she has Gelebration which is a curl enhancing spray gel, also not heavy.

You should try a sampler pack. Also, I just started out by washing less and slowly it's gotten to be even less. I wanted to be CG but it just didn't work for me in the beginning so I've just learned to do what works for me and whatever my hair wants that day. I guess I'd call myself modified CG but my hair is a whole lot healthier than it used to be, that much I know!
2b/3a, primarily use Jessicurl and DevaCurl products, Curls Hair Tea conditioner and various gels. I'm modified CG-ish since 5/04.
