After searching for a good shampoo and conditioner to take care of a consistent itch from hard, hard water here in Germany, I found the Malibu C Scalp Wellness Shampoo and Conditioner. Like magic, the itch no longer bothers me, and the itch was with me for over 20 years. In addition to the shampoo and conditioner, I also use the Malibu C Hard Water Natural Wellness Treatment. What a relief the three products give me. I highly recommend this combination if you have hard water.
