One shampoo that I have used is Head and Shoulders Classic Clean shampoo. I have noticed that Head and Shoulders prevents flakes and dandruff. It also leave my hair squeaky clean and shiny. I have used it for years and love it. I recommend that you use it once or twice a week along with the conditioner, especially in the summer time.
