Forget the ones in your drug stores or grocery stores and spend a little extra money and buy a good shampoo and conditioner from a salon. Many store bought shampoos contain wax (makes the hair shiny.) Here is a good tip I just learned. Once a week mix warm water (approx. 1/4 cup) with 1/2 cup of baking soda and mix into a medium thin paste and apply to hair. Leave in for 15 minutes and then shampoo with a good shampoo. The mixture of water/baking soda takes out all the gels, mousse build-up, etc. It really perks the hair up. If your hair is long you will need to mix more water and baking soda.
