I had been using it since Nov 04 up until the beginning of April, and my hair always felt strong, and looked shiny, but it does strip the hair. IMO, all Nexxus shampoos strip the hair, because of the SLS. I am selling my Botanoil and Therappe, because I stumbled upon Creme of Nature shampoo, which IMO, is as gentle as baby shampoo on my hair, yet very moisturizing.
