I have severely dry, damaged, bleached hair. I mean it's super fried, so one day I decided I wanted liliac colored hair. I purchased a tube of permanent lavender hair color from my local cosmoprof store and went ahead and applied it as directed. Well, my results weren't so great since my hair was FRIED. The color turned by roots BLUE and my ends a sickly GREEN/GRAY color. It was gross! Working in a hair salon, I went to work pretending, like I meant to do that. Needless to say, it was a reflection on my salon (even though they didn't do it), the owner pulled me aside and handed me a packet of Malibu Color Correct. I looked at him like he was crazy, I didn't think this was going to work. I went home and tried it as directed, and let me tell you, it pulled ALL the unwanted color out of my hair. My hair was back to it's platinum blonde state. The best part of all, it DID NOT damage my hair, at all. My hair felt soft and looked healthy after this treatment. I can not recommend this product enough. I absolutely love it, it's a true miracle worker!
