As I am all about natural and healthy shampoos, I heard good things about this vitamin shampoo and was curious to see the results. The first thing that intrigued me about this product was the fact that it is sulfate and paraben free! I naturally have a not-so silky hair, and in the past, I had difficulty finding the right combination, a vitamin-based shampoo that leaves my hair smooth and shiny until I tried this shampoo! It is very nutritional for my scalp, because it contains a tremendous number of vitamins, B, C, D, etc., you name it. I also love the fresh smell of Acai Berry, and feel so refreshed and relaxed after washing my hair; it gives me the same feeling I have after leaving a spa. I have a friend who has her hair dyed and she was curious to try it to see if this shampoo maintains the color; she was pleasantly surprised to learn that she can use it for her color-treated hair, too. Although in general, I am not prone to developing dandruff, since I started to use this product, I have not noticed any dandruff, as it happened to me before with other brands. I am very pleased with this shampoo and I will definitely continue to use it. I enthusiastically recommend it!
