There's a poster on here called kathymack who sells sample sizes of curly products, I think she has a link in her sig if you can find one of her posts so you can get in touch with her. Other than that I'm not much help - fighting the same battle as you, in fact your description of your hair could have been written for me too. I'm quite paranoid about my thinning top, it's so depressing.
