I began using Purology Anti-fade Moisture Shampoo and conditioner when I had my hair colored and highlighted.  The shampoo and conditioner were sold together and seemed to be the most expensive hair products I have ever purchased.  Before this my hair was dry and dull.  Now it has shine and real life to it and certainly was worth every penny.  One great feature about this product is the fact that use use very little to get great lather.  The sage fragrance is just wonderful, and combined with the mint fragrance of the conditioner, it is so invigorating.
