Why Is Hard Water Not Good for Your Hair?

Hard water can damage your hair in many ways

Water that contains a high level of minerals and metals is not necessarily bad for your health — you can drink it if it is safe for consumption — but it certainly can be damaging to skin and hair.


It’s thus no surprise that many homeowners get expensive water softeners installed in order to combat hard water on a day-to-day basis. Indeed, even industries prefer soft water since hard water leaves behind buildups, damages plumbing, and interferes with chemical processes.


For most of us, a new day begins with a relaxing and gentle shower that leaves us feeling clean and refreshed.


But if it is hard water coming out from your shower, chances are that you aren’t going to experience that sweet, sweet post-shower bliss. Instead, you’ll be lamenting the sorry state of your hair and dreaming of the smooth and gentle feel of soft water.


So, how does hard water damage hair? Let's find out.


5 Reasons Why Hard Water is Bad for Your Hair


Yes, that’s right. Hard water wreaks havoc on hair. But why? And how? Let’s find out.


1. Hard Water Can Cause Itchiness and Dandruff


Hard water is full of salts of calcium and magnesium, and these tend to accumulate on the surface of the scalp. The minerals in hard water also react with the ingredients in your shampoo, leaving deposits on your hair and making the shampoo less effective. Thus, with the pores of the scalp clogged, it becomes difficult for your hair to get moisture.

But does hard water cause dandruff? It seems that it can. Over time, hard water makes the scalp dry, cracked, and rough, causing itchiness and flaky dandruff.


2. Hard Water Can Make Hair Weak and Prone to Breakage


As explained in the previous point, the minerals in hard water often react with hair products and leave a film of unwanted deposits on your hair and scalp.

Unfortunately, your hair will get weighed down by these residues and become weaker as a result. Often, you will find yourself using more shampoo to get rid of the buildup on your head; however, doing so will only strip away your scalp’s natural oils, making the hair frail and listless.


Clearly, regularly using hard water for showering makes hair prone to breakage. So, does hard water cause hair fall? It seems as though, over time, hard water can indirectly lead to hair fall.


3. Hard Water Can Make Dyed Hair Fade Quicker


Usually, hard water contains iron, chlorine, and copper, along with salts of calcium and magnesium. These metallic elements can greatly damage coloured hair; iron, in particular, oxidises and can lead to brassy tones in blonde hair and coppery tones in brown or black hair.

The ion deposits from the salts in hard water can also change the colour and accelerate the fading of dyed hair. Plus, people have a tendency to use more shampoo to combat the effects of hard water, which in turn can cause hair colour to fade more quickly.


So, if you are in love with the gorgeous colour your hairstylist has bestowed upon your hair, stay away from hard water!


4. Hard Water Can Cause Frizziness


The minerals in hard water are not gentle on your hair. Thus, it’s not surprising that most people find themselves trying to tame frizzy hair after taking a shower with hard water. Now, dealing with frizzy hair just once counts as a bad hair day. But dealing with frizziness every single day? That’s a serious matter that needs immediate attention.

Over time, the frizziness caused by hard water can lead to dry, brittle hair and split ends.


5. Hard Water May Cause Hair Thinning


Although hard water does not directly cause hair thinning and hair loss, it certainly creates an environment that can foster such issues in the long run.

Mineral buildup can prevent your scalp from absorbing necessary moisture, which can lead to weakened and thinning hair over time. Frequent hair washing — as a means to get rid of the buildup — can further cause hair to become dry and limp, giving the impression of reduced volume.


Plus, hard water residues may also interfere with hair growth as they can prevent blood from properly reaching the hair follicles.


Say Goodbye to Hard Water and Hello to Soft Hair!


Clearly, taking showers or baths using hard water is not a good idea, and your hair will certainly not thank you for it. As explained above, the high mineral content in hard water can make hair dry, brittle, and difficult to manage. It can also cause buildup on the scalp, which can lead to dandruff and other itchy scalp conditions.
