I love Malibu C Color Prepare and Hard Water Wellness Collection. My stylist started me on it years ago. It really brought out the shine and silkiness, and reduced the dull, brassy look that was associated with the water where we lived in Pennsylvania. I recently moved to Arizona and now out of products. The water here is so hard and contains lots of minerals and I've noticed my hair becoming weighed down again. So happy I found your website!
