I have very hard well water. Color does not "stick" to my hair. My hair tends to be dry, brittle and very frizzy. After one use of Malibu C Hard Water Wellness shampoo, conditioner and wellness remedy, I noticed a difference. My hair wasn't frizzy after blow drying and it was very soft. I have also noticed my blonde hair isn't as dingy-looking after one treatment with the Hard Water Wellness Remedy. Highly recommend this product!
