I had heard about this online and wanted to give it a try as I just went from brunette to blonde for the first time. I've been researching various shampoos that are safe for color-treated hair and I finally found the one. This made my hair feel very light, fluffy and soft. I washed my hair 4 days ago and my hair still feels pretty clean (with a couple of sprays of dry shampoo)! I let my mom try this too and she quickly bought a set for herself. This Nioxin set is definitely worth a try!
