Hi there! I'm 2a/2b and have been CG for about 4 months. So far I've liked it. The CG method has drastically increased moisture levels in my hair and cut down frizz (and I had a TON of frizz before). My hair has also gotten wavier and even spirals now. Unfortunately I've lost volume, and I'm looking into clipping/diffusing techniques to help add back the volume I had when my hair was drier and straighter. Because I live in Asia, I haven't really had the chance to experiment with tons of curly, CG-friendly products, but I'm already finding some products/recipes that are working. So far I like the results of doing the CG method, but I'm not there yet. There's still a lot I need to learn/try.
The most important thing about your hair is not your curl type (2a, 4c, etc.) but hair properties... porosity, texture, density, elasticity. This site has great explanations on what those categories are and how to figure them out. They also do a hair analysis if you're up for it. Live Curly Live Free - Curly Hair Basics
Your hair properties will best determine what products you should be using. Curlies on the board tend to write their properties, products and techniques in their signatures, so you can look around to see who has similar properties and see what they're using/doing.
Do read the stickies on the "newbies" section. If you're really interested in doing the method I would highly recommend getting the Curly Girl Handbook. Another two topics that I find highly important in doing the CG method successfully are understanding "protein/moisture balance" and "dew points and humectants." You can use the search function to read many articles and threads on this site and inform yourself about these topics. Good luck!
