Best Shampoo For Hard Water [Reviews + Buying Guide]

Hard water is not considered a health risk but can be a nuisance around the home and not just for your appliances and plumbing but also for your hair. It can actually damage your hair and create further hair problems.

Hard water contains more minerals than soft water, mostly calcium and magnesium. If you wash your hair often with hard water, these minerals form deposits on your hair and scalp. This build up prevents moisture from getting inside your hair.

Your hair becomes dry, dull and weak. The deposits can also cause dandruff-like flakes on your scalp. No amount of oil or moisturising conditioners will help you.

Mostly swimmers and people who live in hard water areas get affected. You may also have visited a new city or country and noticed that your hair felt differently. No matter how well you moisturise it, it still feels frizzy and clumpy. Sometimes it feels greasy because all the oil you are applying never gets absorbed. The problem is most likely the water you are using.

There are a few DIY ideas you’ll find online for dealing with hard water on your hair. They include rinsing with lemon or vinegar, installing a shower filter or using bottled water.

But there is an easier way to keep your hair healthy and well-moisturised when using hard water; use a shampoo designed specifically for hard water.

These shampoos contain ingredients that rid your hair of mineral build up. They restore your hair’s natural shine and soften it.
