For years I have struggled with what I thought was dandruff and itchy scalp plus hard water. I never thought about the fact that hard water leaves metallic debris in the hair and that's why I thought I had dandruff. I literally tried everything from scalp shampoos to home remedies to try to treat the problem. Once I discovered Malibu's Scalp Wellness Shampoo and Conditioner and the Hard Water Treatment my scalp issues subsided and eventually disappeared. Thank you Malibu for such an amazing product!
