My husband enjoys using this shampoo and would purchase it again. However, I can't say that he is all that aware of the relative merits of one shampoo over another. He likes to buy a huge bottle of something at a big box store and use it until he finishes it completely. Until lately, he was working on an institutional-sized bottle of Pert. If I say "Honey, there is a new shampoo that will make your hair thicker and more attractive" he will say "I still have eight months of daily shampoos left on my old shampoo." That's the way he is.
