My husband and I began to notice major changes in our hair when we had to convert to using well water about four years ago. Our hair became dry and brittle and actually lost color. Our scalps were itchy and dry. I tried every product I could find off the store shelves to put some moisture back, but nothing worked. Then, I lucked upon Malibu C by doing an Internet search. We have been using the Malibu C Shampoo and Conditioner for quite some time now. We both love it and could not live without it. Within just a few uses, we began to see the results. It only takes a small amount with each use, so we buy the liter bottle and just keep our first-purchased smaller bottles refilled. We will never again use anything but Malibu C products.
