When we think of hard water as an issue, we are often caught in the aesthetic impact it has in leaving hard chalk-like stains on our taps, tiles, and floors.

What we fail to realize is that, if hard water can leave stains like that on our faucets and pipes, imagine how strong of a residue it is possibly leaving on our hair and skin!

In this blog, we will explore how hard water is affecting our hair’s health in ways we weren’t aware of, why this happens, and how we can protect our hair from it.

What is Hard Water?

Hard water is water that contains a high amount of minerals. When you read this, you might think “Well, what’s so wrong with having a high mineral count?” Of course, there isn’t anything inherently wrong with it. But…

The minerals that are mostly present in hard water are Calcium and Magnesium. These elements are known for their highly adhesive behavior, which leads to the formation of limescale (the hard chalky deposits) in your bathrooms, kitchen sinks, electric kettles, etc.

How can Hard Water Affect our Hair?

As we said, hard water contains a high amount of Calcium and Magnesium. These minerals leave behind a chalky residue on our hair.

This buildup can lead to issues like dry, brittle, flaky and damaged hair, and can also lead to an itchy and irritable scalp.

Additionally, these harsh minerals don’t react well with soap and shampoo, making it harder to lather, difficult to wash off, and can leave behind a soap residue that weighs your hair down and makes it look dull.

Effects of Hard Water on Hair

When we experience issues like hair loss, brittle and flaky hair, and dry scalp, we often jump immediately on the “Hair Care” wagon and invest so much money into buying products that will help solve these issues.

But when the product doesn’t work the way we wanted, we go looking for more products and spend hours in research! In this vicious cycle that consumes our time and money, we often overlook the impact the water in our home has on our hair.

Of course, these products can help temporarily, but as long as the water in your home is working tirelessly to make your hair health worse, you’re practically sending your money, time and efforts down the drain.

Here are a few major effects hard water has on your hair:

Dry & Itchy Scalp
Hair Thinning & Brittleness
Frizzy & Tangled Hair
Hair Fall & Breakage
Chemical Buildup on Scalp

Dry & Itchy Scalp

No one likes a dry, itchy scalp. Hard water elements (like Calcium and Magnesium) are harsh on your hair and scalp and strip them of their natural oils.

Also, because of hard water’s property to NOT let soap or shampoo lather better, the products are often stuck in your scalp and hair strands.

This product buildup often leads to clogging of the hair follicles, making them dry and itchy, and in worst cases, it also causes dandruff and scalp acne!

Frizzy & Tangled Hair

When your hair is constantly exposed to hard water, it loses all moisture and natural oils, which then leads to terrible dryness. When hard water causes dryness of the scalp and hair, it automatically leads to frizziness.

This makes your hair appear very dull and damaged which can sometimes make your overall look seem ungroomed.

In addition, the frizziness of hair makes your hair not so easy to manage, and leads to more tangles!

Hair Thinning & Brittleness

Hair thinning and brittleness are major hair health issues but are often overlooked when it comes to hard water. We’ve seen multiple times in this article how hard water has harsh elements.

When your hair is exposed to harmful water like that for years straight, it not only strips your hair and scalp of natural oils and moisture, but it also starts to block your pores and clog your hair follicles.

When your hair follicles are blocked, it allows no room for growth and instead makes your hair brittle!

This can also make your hair lose all its strength and strip it of its thickness.

Hair Fall & Breakage

Hard water is known for reacting badly with soap products, not producing lather and leaving a soapy film. When this happens continually, over a period of time the product builds up in your hair follicles and blocks all pores. This blocking of pores deprives your hair of nutrients and moisture and makes it very weak.

So if your biggest question throughout this article was, “Does hard water cause hair loss?” then sadly, YES.

Hairfall due to hard water is very much a reality and a possibility than many would like to admit.

Chemical Buildup on Scalp

With all of these negative effects of hard water, you would’ve noticed the main problem starts with a chemical buildup on hair and scalp.

This buildup can purely be limescale-like residue and/or product buildup of shampoo, conditioners and hair gels.

When hard water keeps clogging your hair follicles, over time it can even lead to long-term damage to your hair and scalp, making it harder for your hair to get healthy and recover.

How to Protect your Hair from Hard Water Damage?

To protect your hair from hard water damage, you can take quite a few steps and remedies. Here are the five best hair care remedies for hard water damage!

1) Use Bottled/Purified Water

We all clearly know that the water we use (or the pipe water in our home) is what is causing us all the hard water damage. So, the natural first remedy you can try out is to use purified water or bottled water to wash your hair!

Using bottled water or purified water to wash your hair is an expensive unfeasible way to deal with this. While it is still a viable option, please keep in mind that modern RO purifiers waste about 50-70% of water, making them a non-sustainable solution to this problem. So, we highly recommend against it.

But, it’s still a viable option if you have the means!

2) Use a Clarifying Shampoo

Clarifying shampoos are (as the name suggests) shampoos that are designed to clarify your scalp and hair of any product buildup. A simple Google search can bring you hundreds of budget-friendly options that can help you get rid of product buildup and make your scalp and hair healthy.

The only problem with this is that clarifying shampoos have strong chemicals (it is needed to remove the product buildup) and can cause heavy dryness.

So, it is advised to use them only occasionally (once in 3-4 washes).

3) Apply a Hair Mask

Hair masks are a great way to moisturize your hair and scalp.

Hard water can be harsh on your skin and hair, and masks like these are a lifesaver to bring back moisture to your hair and make it healthy.

There are many homemade remedies you can try with ingredients in your kitchen and it costs you nothing! You can also find specific masks for your hair and scalp!

4) Try an Acidic Rinse for your Hair

Most of the hard water damage in hair starts at the scalp. Just like a clarifying shampoo that gets rid of buildup, you can also try an acidic rinse for your hair.

The process is super simple:

Mix 2 parts water with 1 part citrus juice
Massage it into your scalp
Let it sit for a minimum of 10 minutes
Wash your scalp & hair as usual

5) Try a Rinse with Apple Cider Vinegar

Just like the acidic rinse, you can try an apple cider vinegar rinse. You can buy apple cider vinegar from any grocery shop and mix it with water to let it do the trick.

The process of doing this is similar to the acidic rinse where instead of citrus juice, you use apple cider vinegar.

Apple cider vinegar is a great option for the rinse because it contains hair-healthy vitamins like Vitamins B and C, and it also lowers your hair’s pH.

How to Solve Hard Water Problems?

So far, we’ve only looked at steps and remedies you can take to protect your hair from hard water. But this raises a bigger question.

Can we SOLVE hard water problems in our home by any means?

If you’re wondering if there’s a way to deal with hard water without having to do multiple remedies constantly, the answer is… YES.

To solve hard water issues in our home, we need to address this problem at its root: The Water.

Treating the water and making it soft is the only way to actually “solve” hard water issues. As long as the water is harmful, all of our other efforts to better our hair health is going to end in vain.

Treat Hard Water in your Home

The phrase “TREAT hard water” can sound like it’s a time-consuming affair of water treatment. But in reality, that is far from the truth.

We now live in a world that has improved so much in technology that we have many simple systems to treat hard water in our homes.

Hard water can be treated and converted into soft water in two ways.

By using water softeners & filters
By using water conditioners

Water Softeners & Filters

Water softeners and filters are systems that remove hard water minerals like Calcium and Magnesium from your pipe water to turn it into soft water.

These systems are a great option to treat hard water but they also lack in certain areas.

The water-softening systems are usually bulky & take up extra space
They need weekly or bi-weekly maintenance
They require salt recharges & cartridge changes (more purchases & money spent)

Overall, they are not the ideal option if you’re looking for a hassle-free long-term solution.

Water Conditioners

Water Conditioners are systems that break down hard water minerals into smaller nano-sized colloids while also neutralizing them. In this process, the harmful adhesive properties of the elements and salts in water are deactivated, and the water is converted into soft water without a need for mineral removal.

A water conditioner has a lot of advantages in terms of:

Requires zero maintenance
Takes up no extra space and can fit within your main pipeline
Zero recurring purchases or expenses
Very sustainable in the long-term & zero water wastage

Now, we know the best option in these two stands out by itself. To make it much easier for you, we’re taking it an extra step and introducing something called a “Shower Water Conditioner!”

Use a Shower Water Conditioner

Shower water conditioners are simple systems that fit within your shower arm (literally as a small pipe) and condition all water passing through it.

When hard water passes through a shower water conditioner, the strong minerals (like Calcium and Magnesium) are blasted through the system, making them break down and lose their harmful adhesive properties in the process.

Use a Shower Conditioner. Shield your Hair from Hard Water!

Now, when you take a shower, your hair is shielded from all harmful hard water minerals because the conditioner has neutralized the elements making them completely harmless!
