I have used TRESemme Moisture Rich Shampoo and Conditioner for several years.  I have been coloring my hair for about 15 years and I don't need a shampoo to protect my color.  Once I started using TRESemme Moisture Rich Shampoo and Conditioner, my thick, course hair drank it up and the color is held much longer!

I can even spend time in the sun and not have the color fade.  This is because of TRESemme Moisture Rich Shampoo and Conditioner!
