The DVD that comes with the "newer" Curly Girl book is fabulous. Book is under $10 or you might be able to get it from the library. It really shows you how to style your hair. I could never use the copious amount of product that they do, but learned a lot.
Many of us start out with Deva products, think we like them and then move on to things that our hair likes a lot better. My salon has the Deva products, but I won't let them use them on my hair. After the ingredient changes several years ago, I even found the NoPoo too drying.
The best way to choose ingredients/products is by hair properties. Here's a link to help you with yours
Live Curly Live Free - Curly Hair Basics Once you determine your properties, look for people with hair like yours and see what they use. It's the best place to start.
