I think I've found a miricle shampoo...!

My cousin (who just graduated from a cosmotology college) told me I had to try the Generic forms of Nexxus Therappe Moisturizing Shampoo and Nexxus Humectress Moisturizing Conditioner available at Sally's. They are amazing!! My hair has been so shiny, and has been softer than it ever has! Has anyone else ever tried these? Does anyone know if they contain any silicones? Should I alternate with another shamppo/conditioner so these don't loose their effects, or maybe just use different ones once a week? (I wash my hair every day.)And, as a side note, I was wondering if any of the Nature's Gate products would act as a good clarifyer. I've heard that'll they'll strip temporary color, so I was wondering if that meant they would be a good clarifying shampoo. ???Thanks so much!!
