I like to keep my hair color as long as I can and love how this shampoo helps me keep my hair color looking new, preserved longer,and protected. Ever since I started using this shampoo I have noticed that my hair has kept its color longer and I also have all the great benefits like shiny soft hair and more volume. Effectiveness This shampoo works great and has proved to me that it works because my hair color has lasted a month longer than what it usually does and is barely fading like it did when I used other shampoo brands. I have gotten many healthy hair benefits and have loved being able to keep my hair color longer. Scent I am very sensitive to a lot of highly perfumed body and hair products but this shampoos scent did not bother me and it actually has a wonderful fresh, clean, natural scent that is not at all over powering and leaves my hair smelling wonderful but yet not overly perfumy.
