I had been living in a building with old (and presumably rusty) pipes for a few months when I started to notice my usually blonde ash hair had become "gummy." dry and an unpleasant orange-ish brown color. I went to a salon and had my hair trimmed and treated with a toner but this did absolutely nothing. The ends were still frazzled and my hair was still orange! So I ordered the Malibu C weekly wellness remedy and used it as directed. After on treatment, my hair was softer and shinier. After the second treatment, the orange color was gone! This product definitely works!
