This is Great... I had hard water at my place and my hair was always dull and lifeless and it seemed dirty all the time. I changed my water softener in my shower an my hair is great. soft with volume and clean. I love it. You have to change your shower head water softener at least once a year or every two years in order for your hair not to go back without life. I didnt know this but did alot of research. Hope this helps if your trying to grow your hair out! =).
