I live in a rural area and use well water. I noticed my hair had been starting to break off (hair loss) and not just a little either. It was substantial. I used your Hard Water Wellness shampoo and I would say within two weeks to a month my hair stopped coming out in bunches. Thank you. I also have tested this. I stopped using your product and again, I started to lose hair. It really works. Again, thank you Malibu C Hard Water Wellness Shampoo.
