Wow! It took me over a year to figure out why my hair was no longer taking color. My well water! My stylist and I struggled time and time again to lighten my hair. I did some research and came across Malibu C and wow, the Hard Water Wellness collection has changed my life. I am finally a blonde again. 7+ months of use and my hair is completely different. I also use the Crystal Gel treatment every few weeks and I feel fantastic. Best product line ever. I wish I had found Malibu C years ago.
