And I love it. Hard water here in Southwest Houston. I used it for 2 days in a row and it made a big difference the second day - hair was much softer and some shinier. I got the conditioner too (it was a set, has the granules that you can use also). I'm using my regular shampoo and conditioner during the week and will do Malibu once a week or so to maintain. Thanks for your April 18 post about chelating shampoo.
