My friend recently purchased a 12-pack of the Malibu C Hard Water Wellness Remedies and has loved it. As someone who suffers from orange/brassy hair tones no matter how much purple shampoo I use, she thought I would like the Hard Water Wellness Remedy, too and let me try a packet. I was amazed by the results.  I get ashy blonde highlights that only stay ashy for about a week and a half before my brassiness peeks through. The results were instant and I was honestly amazed. My hair was just as ashy and toned down when I left my hairdresser's chair. I'm buying this stuff in bulk! It is my new holy grail hair product!
