Last year I bought some shampoo in San Francisco and absolutely loved. Or more importantly my hair loved it. I had never heard or "Argon" and was curious after listening to the rep. Well I was very happy to see Susie's carried it and my hair has never been better. i have very curly hair which can be a problem at times due to the frizzies etc. The control and individual curls that now adorn my head is fantastic.
