Water hardness refers to the percentage of mineral salts that water contains. Hard water has a high concentration of dissolved minerals, specifically calcium and magnesium, but may also include copper, iron, and chlorine. Soft water, such as clean rainwater or distilled water, contains very few or no calcium and magnesium ions.
Our list of suggested products is in the second part of this post.
If you travel across the country, you will find that your hair care products vary in effectiveness and your hair will behave differently from place to place. When you are in a hard water area, the minerals in water interfere with the cleansing agents in your shampoo, making it less effective. It takes longer to create a lather and you need to use larger quantities of the products even if they contain sulfates. When used with soft water, shampoo or body wash lathers more quickly and cleans more effectively than with hard water.
The high mineral content in hard water is difficult to rinse out completely, which can cause a mineral buildup in your hair. The same chemical compounds in water that cause a whitish scum on your bathtubs and shower curtains, also leave deposits on the surface of your hair. You add more and more build-up with every hair wash, without even realizing it.
Many people are not aware that the water they are using for washing and bathing has an impact on their skin and hair. Around 85% of American people live in areas with hard water. Hard water is considered healthy to drink, but it can have adverse effects on your skin and hair and can cause scale deposits on household appliances. If you live in a hard-water region, special precautions should be taken to protect your hair from the damaging effects of water hardness.
The Effects of Hard Water on Hair
If you live in a hard water zone you have probably noticed the negative effects of mineral deposits and metal traces on your hair. A high concentration of minerals, such as Calcium, Magnesium, Iron, and Copper in your water can damage your hair and cause it to look dull, limp, and unmanageable. Some effects like dullness or brassy orange tints are easily noticeable, while other damaging effects may slowly accumulate over time before becoming obvious.
- Greasy and dirty looking hair: Minerals dissolved in water form deposits on your hair weighing it down. Your hair may feel sticky and dirty near the scalp, no matter how often you wash it. At the same time, your ends may become overly dry and prone to splitting and breaking.
- Changes in hair color: Mineral deposits and the high content of iron in hard water can cause color fading or even affect the results of salon coloring services. Iron in water acts as an oxidizer, causing brassy tones in light blonde hair and coppery red highlights in dark hair. The more you wash your hair, it will continue to turn more orange. Blond highlights may look orange even with a water softener system installed.
- Dry and dull hair: Mineral scales can cause your hair to look greasy. You need to wash your hair more frequently and to use more shampoo. Over-washing leaves your hair dry, straw-like, and brittle while your scalp may feel itchy and flaky. The mineral build-up also causes loss of shine, leaving your hair looking dull and lifeless.
- Unmanageable hair: Frequent washing and use of sulfate-containing shampoos will disrupt the cuticle layer, increasing the rough texture of your hair, making it prone to frizziness, and full of split ends. Rough hair gets easily tangled and may be difficult to style. Damaged hair doesn’t hold curl well and your perm will fade faster.
- Thinning hair: Mineral build-up affects hair’s elasticity, making it more prone to breakage. Hard water buildup on the scalp may clog the roots and interfere with the growth of new hair. Calcium deposits on the scalp may cause dry and itchy scalp with powdery flakes.
How to Prevent Mineral Build-up from Developing
Soften your water: Installing a water softening system throughout your entire home is a good way to deal with hard water. The minerals and metal cations are eliminated before they get to the tap, resulting in softer hair and skin.
