I used Malibu C Hard Water Wellness Remedy on a client to remove the buildup on her hair. Her hair had quite a buildup on it! She was sure it wasn't going to work since most other products she had tried didn't do much for her. So i put it on as directed and put her under the dryer. Once we styled her out, she was completely amazed by the difference it made in her hair! She now a believer in Malibu C! Thanks!!
