"Jason Naturals" also sells shampoos without lauryl sulfates. They have quite a lot of varieties. I think that a shampoo with Tea Tree Oil would suit your hair type. You can buy Jason brand shampoos from the Whole Foods chain markets.
Or you can buy from websites like Vitacost.com
I happened to discover this website when I decided to shop for natural/organic personal care items. the website offers 38% off, which I find great. I select the products that I want to buy by visiting the nearby Whole Foods store, but buy them online.
