Good shampoo and conditioner?

What are good curly shampoo and conditioners? Im a 3a-3b, and I have tried this insanely expensive argan oil shampoo and conditioner which was impractical for my medium-thick hair. It worked well for a couple of weeks, and then stopped. I clarified after that, but it never worked as well as it did. I wasnt getting the results I wanted for something way out of my budget.
At the moment I'm using a Dove conditioner, which I'm guessing is not moisturising enough. It's just a waste when Im using expensive styling products, and still dont get any results. So which ones are you using out there?

I've recently found Natural Instinct shampoo and conditioners which are very affordable and CG friendly .. I also use tresemme naturals conditioner and they are very good for value and quality.
Im not CG, but I try to avoid cones. I may have a look at tresemme though. Thanks for that!
