WaterSticks is the inventor of the ShowerStick shower water softener. The ShowerStick makes it possible for you to have soft water while showering without having to install a costly whole house water softener. It contains softening resin beads and works via ion exchange as a whole house water softener does to remove hard water minerals such as calcium and magnesium. And it’s portable, so you can take it with you if you move! A filter mainly removes chlorine but doesn’t remove any hard water minerals. People purchase many different types of filters but aren’t always happy with the results which is most likely because they’re still showering in hard water. But since the ShowerStick is a softener, it will remove those nasty hard water minerals that are notorious for causing all kinds of skin and hair issues. Do you suffer from dry, itchy skin or psoriasis or eczema (dermatitis)? Do you have dry, brittle, frizzy, straw-like hair? Are you experiencing hair thinning or loss? Is your hair color fading? Are your shampoos and soaps not lathering? Is there hard water buildup inside your shower and on your glass shower doors? The white chalky limescale residue buildup on your glass shower door and on your fixtures (especially caked onto the aerators) is hard water. It’s the same thing that builds up on your skin, scalp, and hair when you shower…yuk! So, remember…the ShowerStick is a SOFTENER, not a FILTER, since it will give you soft water. What exactly is “soft” water? It’s water that’s lacking hard water minerals such as calcium and magnesium. And it’s easy to prove that a filter doesn’t remove minerals and a softener does by using a water hardness test kit.
