Using Malibu C Hard Water Wellness Collection has caused a major improvement in my hair! It is now a 'must have' for me. The Hard Water Wellness Remedy packets remove residue and make my hair manageable again. I have light blonde hair and this product keeps the brassiness at bay. The Hard Water Wellness Shampoo and Conditioner are wonderful to use in between use of the Hard Water Wellness Remedy. Blondes out there, give this a try if you have hard water! You won't be sorry!
