Many of us start with Deva, think we like it and then move on to other things we like better. Hair properties are a good way to help choose ingredients/products that might work for you. Here's a link Live Curly Live Free - Curly Hair Basics
Once you determine yours, you can look for folks with hair like yours and see what they use (in signatures.) It's the best place to start.
My hair prefers the more natural products from the online boutique type companies. I stay away from a lot of chemicals (polyquats 4 and 10 build up and cause frizz for me.) Many of us rotate products because our hair satiates on using the same thing all of the time. I wet, use a rinse out and style every day. Seldom use any one product more then once every five days, if that.
