I have started to reread her book and I am going to actually do her whole regimen for a year to see if I can gain the whole 6" or more. ( I was inspired after seeing Glamour Girl's success). I use to use Creme Conditioning Shampoo by Elasta QP and it stated on it's label that it is ph 5.5 . It's for dry/damaged hair. My hair felt really nice after using it. Right now I am experimenting with all natural shampoos from the health food store that are moisturizing but I usually just condition only wash which I am going to incorporate into the routine because my condition washes get my hair pretty clean and my hair has done really well with them. ( I do not have a camera right now but I am going to get one to track my progress and hopefully post).
