What exactly is hard water?

When water has a very high content of minerals like magnesium, chlorides, salts, copper, iron etc, in each water molecule, then that water is called hard water.

It is important to note that all rain water is actually soft water (or water that doesn’t contain any mineral deposits). 

But over time, this rain water seeps into the layers of the earth and eventually absorbs these minerals.

So when this water comes through our taps at home and we use it, it affects our hair.

Hard Water vs. Soft Water

A lot of people may have this question in your minds – how do I know if the water I use is hard water?

Well, there are some indicators that you could look for to check if the water you are using is hard water or not.

Firstly, if you are using hard water to wash your hair (or even just your hands for that matter), you will find it hard to get your soap or shampoo to lather up.

This will not happen in the case of soft water, because any cleansing agent lathers up easily in soft water.

You will also find a difference in the taste of the water you are drinking. Hard water has a really distinct taste as compared to soft water (yes, hard water actually has a “taste”, a weird one).

Hard Water Effects on Hair

As I mentioned earlier, hard water has a heavy content of minerals and when we wash our hair with that water, these minerals enter into our hair strands and this is because they make the hair cuticles more prone to opening up.

Once these minerals enter into our hair strand, it can affect the hair in many ways. Check out what are the hard water effects on hair and how you can prevent it.

1. It can clog the hair follicles and inhibit hair growth

Using hard water can inhibit proper hair growth and this is because hard water contains the mineral calcium. 

When hard water is used on our hair, this calcium mixes with the shampoo and forms a layer of scum on our scalps, clogging the hair follicles and getting calcified (or hardened). 

Therefore, there will not be sufficient blood flow to the hair follicle to produce new hair, thus inhibiting hair growth.

2. Can weigh the hair down

When we use hard water on our hair, there can be a possibility that the mineral deposits from the hard water get deposited onto our hair and form a coating around the hair strand. 

These mineral deposits also combine with the dirt, oil and buildup on our scalp and make the hair look greasy and weighed down. 

When the hair is weighed down, it will result in hair that looks dull, lifeless and stands limp. 

For those using hard water to wash their hair, they will find it very hard to make their hair achieve a nice voluminous look.

3. It can strip hair dye color-treated hair

Hard water is an enemy to those with color-treated hair because it will make the color fade much earlier than it is supposed to. 

This is because the mineral deposits in the water can alter the color, either discoloring it or causing it to fade.

4. Makes the hair feel greasy

There are many ways as to how hard water can make the hair feel greasy. 

Hard water will make it harder for moisture to enter into the hair, which could lead to over-conditioning the hair resulting in it becoming greasy.

If hair becomes greasy, people tend to overwash it; stripping the hair off its existing moisture and making it dry, in turn stimulating the sebaceous glands to overproduce sebum. 

When the sebum mixes with the mineral deposits from the hard water, it can make the hair look greasy.

5. Makes hair prone to breakage and hair loss

A lot of people who use hard water to wash their hair find that their hair loss is relatively more. Well, this is because hard water makes the hair become dry and brittle. 

When the hair is dry, it becomes more prone to breakage and hair fall.

So just to put it out there, hard water will not have a direct effect on your hair falling out, but it makes the hair prone to breakage, which indirectly is the cause for the hair loss.

6. Hard water can cause the hair to become frizzy

Hard water can be one of the main causes of hair frizziness because the minerals in hard water coat the hair with a mineral buildup. 

This will make it harder for conditioners and moisturizers to enter into the hair shaft and over time, our hair will begin to dry out and become frizzy.

7. It can stain bleached blonde hair green color

Hard water can be a menace to those with blonde or even light-coloured hair. This is mainly because the minerals in the hard water tend to stick to the protein bonds in our hair strands. 

Over time, it makes the hair have a greenish tinge.

Now the same effect can take place irrespective of hair color, but fortunately, the greenish tinge will not show on darker hair shades as compared to the lighter ones.

8. Can make hair look brassy

A lot of people with blonde or light hair colors complain of hair brassiness and this could be because of the hard water they use to wash their hair. 

The mineral deposits in the hard water are responsible for coating the hair shafts, making light hair turn brassy with hues of yellow or orange.

Ways to protect hair from the effects of hard water

1. Get a water filter

This is one of the most effective ways to help reduce the effects of hard water on your hair, is by targeting the source of course. There are shower filters or water filters which can be attached to your shower heads or taps.

When these water filters are in use, they will help treat the hard water by filtering out the minerals and other impurities.

There are also built-in water filters that you can install for those who live in places where the municipality supplies only hard water, but this is definitely a more expensive option.

2. Keep your hair moisturized

If you use hard water to wash your hair, make sure to moisturize your hair, apart from just conditioning it after a shower. 

Your hair requires this additional moisturizing and it can be done by massaging your hair with a lightweight warm oil a couple of times a week, using a leave-in conditioner and by using deep conditioning masks on a regular basis

3. Clarify your hair

Clarifying shampoos work both ways. While they are very helpful in breaking through the hard water mineral buildup and cleansing the hair, it can also strip the hair off all its natural oils in the process.

So using a clarifying shampoo from time to time (a maximum of once a month) is okay, as long as you deep condition your hair after to help your hair regain its lost moisture.

4. Use a sulfate-free shampoo

In my opinion, irrespective of what your water type is, you should still use a sulfate-free shampoo, because sulfates can dry your hair out extensively.

That being said, using a sulfate-free shampoo when washing your hair with hard water is essential because otherwise the sulfates can react with the mineral deposits in the water and further damage the hair.

5. Try the natural way with apple cider vinegar

If you are vary about using a clarifying shampoo, then you can try the all-natural method – apple cider vinegar. It will help get rid of the mineral buildup, while also increasing hair luster and shine. 

So all you need to do is combine half a tablespoon of organic apple cider vinegar, in 1.5 cups of water, apply it all over your hair, leave it on for a bit, before rinsing it off. 

You can follow this practice every week.
