There are different aspects to cg. The part that most improved my hair was not shampooing every single day! which I used to do. Shampooing less frequently (even though I use a mild sulfate shampoo at least once a week) made a big difference to me.

I'm undecided whether using cones or sulfates makes a difference to my hair. Everyone's hair/curls are different - so you needn't feel like a failure at all if your hair doesn't respond to the party-line cg message. Maybe a change in technique is all that you need.

Good luck and please let us know how you are doing over time!
