Many wavies and long hair straighties conditioner-only wash and are sulphate and silicone free successfully. CG is largely about healthy hydrated hair, that has the potential to work for almost any hair type. CO-washing may not work for those with a scalp problem or those who have very fine thin hair who benefit from the 'pouf' that shampoo can give.

Wavies generally don't know their true curl pattern whilst using commercial products and standard techniques - brushing, combing, towel turbans and silicones can all pull out curl. It's more important to know your hair properties that your curl pattern anyway as that will help you choose appropriate products and ingredients.

It's worth working your way through the stickies on the newbies board and general haircare board, plus some of the articles on the main NC site especially those by 'curl chemist' Tonya MacKay. If you are still confused by properties you might consider having a hair analysis done, either Live Curly Live Free (cheaper but generic information) or Komaza Care (more expensive but very detailed).
