I have been fighting hard water mineral buildup in my highlighted blonde hair for years. After much research and recommendation from my stylist, I found your Malibu Blondes products. I am soooooo pleased! The results are amazing! I use the Malibu Blondes Shampoo and Conditioner every day and the Blondes treatment packet every two weeks or so. The shampoo and conditioner leave my hair soft and shiny with much volume, as I have fine hair. These products have helped tremendously to keep my blonde highlights vivid and bright and also keep the brass color out. I will be a long-time customer!
