Kevin Murphy has introduced a shampoo that will brighten up those blonde shades. It’s a purple based cleanser that helps neutralize those yellow tones that seem brassy. The benefits of this sulfate and paraben free shampoo are refreshing blonde tones, and adding shine with Murumur, Shea, and Mango Seed Butter. There’s also Sunflower Seed Oil which is a natural sunscreen to help protect you color from fading. I would use this just for brightening up your color when you need a little refreshing, so at most once a week. Continue using a color safe shampoo for your other washes.
