I started to air dry and stopped using heat (caruso rollers) I only use heat to dry my hair now when I am like at week 10 or 11 without a relaxer. I relax every 3 months. The heat helps me to manage my hair during that period. I don't use any of her recommended shampoos and I don't relax every 6 weeks. I think u she is more for the beginners and u may be beyond her.
If you type "Carolyn Gray" or "ponytail method" into the search box, you'll pull up all kinds of info on her method. She even developed her own hair oil!
If you want to see someone whose had success with her method, check out Cheryl Frank's photos here
Just click on photos. (I'd post a direct link to the photos, but I don't know if there's a rule against it...)
