We have the hardest water there is and I knew it was damaging my hair, which is already color treated and naturally dry and curly. I installed a shower head filter that was supposed to help but even that didn't really help much so I assumed there wasn't anything I could do about it. My cousin told me about the Malibu C Hard Water Wellness Remedy and I saw a major difference the first time I used it. I've used three packets so far one every week, and will definitely be buying more. I had no idea something like this existed. My hair is softer and less frizzy when straightened, which was one of my major concerns. My color looks great, too.
