Though I'm from NY, where the soft water leaves me with shiny, bouncy hair, here in LA, my hair is dull, unmanageable and frizzy. After prolonging my professional blowout for as long as possible, I was reluctant to wash my hair, knowing how hard the water in my 1930's LA apartment is. I used the Hard Water Treatment. I let my hair air dry before blow drying it. It was soft, calm and shiny and became even shinier when I blew it dry. WOW! I can't wait to try the Hard Water Wellness Shampoo.
