I had such VERY bad well water that I spend $100 a month treating plus a speciall filter for my shower head but nothing seemed to work for my hair. I could wash it in the morning and by 12:30 in the afternoon it would be greasy already from the water and always felt unclean, plus the water had created an orange tint to my very blonde hair. Immediately after one wash with Malibu C Hard Water Wellness Shampoo and Conditioner, I noticed a difference. My hair was so clean and the color was so bright! It really does work wonders!! I would recommend these products to everyone!!
