I live out in the country so we have to use well water which has always been plagued with iron my entire life. After having short hair for a long time, I decided to grow it out longer and with that came the orange hair. It was brassy and brittle. The only way to remove it was through bleaching which only wrecked my hair more. After years of being told to use purple shampoos, which didn't do a thing, and suffering through orange-blonde hair, I was told by an Ulta employee to try Malibu C's Hard Water Wellness Kit. Even after the first use, I could see a noticeable difference. I leave the Hard Water Wellness Remedy in my hair for quite some time, and I can tell it's working, by the awful iron smell that follows.
