I. Let’s Start With The Basics - What Is Hard Water In The First Place?

 Hard water is water with an abundance of dissolved mineral content, the most common minerals being calcium, magnesium, and iron. It refers to water that’s full of minerals, which doesn’t necessarily sound like a bad thing, right? Though it does not harm your internal health, the problem is that these minerals build up and harden your hair, ultimately leaving it dry and brittle. Besides, those with sensitive scalp can become irritated and inflamed, especially if you have a history of sensitive skin, psoriasis, or eczema.

II. How To Tell If You Have Hard Water?

 Though stiff and dull laundry, dry and itchy skin and deposits left on faucets and dishware are good indicators you have hard water, there’s a quick and easy test to determine once and for all if your home’s water is hard. To perform the test, grab a clear plastic water bottle with a cap and clear, unscented soap and follow these steps:

1. Fill A Clear Container With Tap Water and Add Unscented Soap

Use a see-through container like a plastic water bottle. Fill it about two-thirds full of water from your tap. Then add about 10 drops of pure liquid soap without dyes or perfumes into the bottle of water. Avoid using soap labeled as a detergent – detergents usually have additives that will affect the test.

2. Shake It Up


 Put a cap on the container and shake it for 10 seconds to mix the soap and water. Open the bottle and look for suds at the top of the water. If there are plenty of suds on top and the water is clear underneath, you have soft water. If the water is cloudy and there aren’t many suds on top, your water is hard. You can add more soap to see how much it takes to get suds, which will give you a sense of how hard your water is.

3. Gradually Shake In More Soap

 Add more soap 5 or 10 drops at a time, shaking the bottle after each batch. The number of drops it takes to make suds will give you a rough estimate of your water hardness:

  • 20 drops: slightly hard
  • 30 drops: moderately hard
  • 40 drops: hard
  • 50+ drops: very hard

→ You’ll see water hardness reported through two different scales: grains per gallon (GpG) and parts per million (PPM), which may also be represented as milligrams per liter (mg/L). Each scale indicates the mineral level in your water. The higher the number, the harder the water. You can use the chart above to find out the hardness of water.

III. Best Shampoos For Hard Water

 Whether or not you have hard water ultimately comes down to where you live but the good news is there are ways to remedy the situation without packing up and moving. Installing a shower head filter and professional treatments are both options, but the easiest (and most cost-effective) fix is reaching for the right shampoo.
