I was a bit skeptical when I bought this product, I bought the shampoo, conditioner, and it came with a freebie blonde lightening spray. I thought how could shampoo really make a difference, but as a blonde obsessed with obtaining the PERFECT blonde coloring, I was willing to try anything! And I'm glad I did, because it works! I was at a stage where my roots were growing in dark, and I couldn't afford the salon, but after a week or two of using the lightening shampoo and conditioner from John Frieda, I could see a visible difference in my hair color. It also helps my blonde to look more natural, as it lightens gently and over time. It looks especially bright after blow drying and styling. Overall, I'm a very happy blonde customer. It smells AMAZING, the conditioner makes your hair extremely soft, and most importantly: it does what it says it will do. It lightens your hair to a perfect, natural looking blonde.
