Hard water is water that contains a large amount of minerals. Mineral content in water can vary from state to state – even from city to city. While it’s not harmful to your health, hard water can bring serious problems to your skin and hair, adding to them a buildup of minerals and drying them out. If you’ve ever moved from a soft water city to a hard water city, I know you can feel my pain. But don’t fret my dears, because hard water does not have to ruin your life!
