Wen, and the Sally generic are loaded with silicones, which coat the hair and can cause build up and brittleness over time. You might want to google "no poo" if you want to give up shampoo. I haven't "poo'd" since January and my teen daughter hasn't since March. We just use $1.38 for almost a liter of Suave Naturals conditioner as our cleanser with great results. My daughter even uses a bit extra as a leave-in (she has thick, VERY curly hair).
