Absolutely amazing! My house runs on well water and we have copper pipes, so our water deposits A LOT of green and sediment from the pipes onto my hair. To make matters worse, I highlight my hair bright blonde, and usually within a couple of weeks of getting it done, it starts to turn greenish/orange. I have tried EVERYTHING (natural remedies, clarifying shampoos from Pureology, Paul Mitchell, Bed Head, Aveda, etc.) and nothing seemed to do the trick until I tried the Malibu C Hard Water Wellness Kit and I was AMAZED at how well it worked! I even saw green coming out of my hair and washing down the drain! I even love how the shampoo smells, and it didn't try my hair our like other clarifying shampoos. I will be buying this product from now on - don't ever get rid of it!! Thank you Malibu C!!!
