My light blonde hair was literally turning bright orange from the iron in our well water! Not only was it discolored, but brittle and unmanageable. When I visited my hairdresser for highlights, she looked incredulously at my hair, and pronounced that nothing could be done. Undaunted, I found Malibu C on the Internet, and purchased  the Hard Water treatment.  I was positively overjoyed that in 20 minutes in the comfort of my home, ALL of the orange deposit was lifted from my hair, and it was once again it's original color, as well as soft and manageable. I'm not one to gloat about a product, but this one deserves a heap of praise!!
