When I moved to Los Angeles recently, I noticed that my hair became horrible and unmanageable. I have very thin hair and it was horrible. I thought it might be because of hard water because I also noticed that my shampoos don't get rinsed well. I tried Malibu C Hard Water Wellness Collection Kit and from the first use, I noticed the difference! Like crazy difference! I also did the demineralization with the Hard Water Wellness Remedy. My hair seemed light and my waves came back (which was not happening before). I would definitely recommend this product, especially to people with thin, long hair, because it has worked so far on mine.
