In my little town, we have hard water and until recently I didn't notice it interfering with my color services. Then one of my clients started booking her appointments every four weeks instead of eight because her color was fading so fast. I decided to do a Malibu C Hard Water Wellness Remedy on her before her color and it took so beautifully and lasted her normal eight weeks! Since then I have used this product on several clients who fade too early and have had the same wonderful results. Thank goodness Malibu C products save my color services!!
