Introduction

Many homes in India get hard water, even if you have a borewell in your home. You might keep trying new hair care products or hair loss products for your hair fall and dull hair, but this culprit keeps damaging your hair.

So, does hard water cause hair loss? Can water really damage your hair? Unfortunately, yes. In this blog, we’ll explain the effects of hard water on hair, water hardness levels and correlation with hair loss, and simple ways to protect your hair at home.

What Is Hard Water?

Hard water is water that contains a high amount of minerals, mainly calcium and magnesium. While these minerals are not harmful to your body, they can be harsh on your hair and scalp.

When you wash your hair with hard water, these minerals stick to the hair shaft, creating a layer that makes it difficult for moisture to enter. This leads to dryness, dullness, tangles, and increased shedding, which are the major signs of hard water on hair.

On the other hand, soft water has lower mineral levels, lathers better with shampoos, and keeps your hair smoother and healthier.

Does Hard Water Cause Hair Loss?

Can water cause hair loss? The short answer is yes! Hard water can cause significant hair loss. But it’s not that straightforward. Let us understand the effects of hard water on hair and scalp, and how it causes hair loss:

1. Mineral Buildup Weakens Hair Roots

The calcium and magnesium in hard water settle on your scalp, forming a layer over follicles. This can weaken hair roots, leading to breakage and thinning.

2. Reduced Moisture Absorption

Since your hair is covered with mineral deposits, it cannot absorb natural oils and moisture. As a result, hair becomes excessively dry and brittle and breaks easily.

3. Hard Water Affects Scalp Health

Hard water can cause:

  • Dry, itchy scalp
  • Dandruff-like flakes 
  • Inflammation around follicles

An inflamed and irritated scalp increases shedding.

4. Hard Water Reduces the Effectiveness of Hair Products

Since your hair is covered with mineral build-up, any serum, oil, or mask you apply just sits on your hair without getting absorbed. Even your shampoo doesn’t lather well, and residue stays behind, weighing hair down and causing buildup. All these effects combine to cause hairfall, thinning, and loss of hair density.

Key Signs Of Hard Water Damage To Your Hair To Watch Out For

There are several signs of hard water on hair. Your hair literally communicates with you when the water is too hard in the form of these signs. Check for these effects of hard water on hair:

  1. Dry, rough, or straw-like texture
  2. Increased hairfall and thinning
  3. White or chalky residue on scalp or hair
  4. Dull hair strands with no shine
  5. Hair tangling easily and breaking while detangling
  6. Hair dyes are fading quickly 
  7. Split ends and breakage

4. Try a Final Rinse With Soft Water

5. Use Apple Cider Vinegar (ACV) Rinse 

ACV helps dissolve mineral deposits and restore scalp pH. Mix 1–2 tablespoons of ACV with a mug of water and pour in the end.

6. Install a Shower Filter

Frequently Asked Questions

What types of water (hard vs soft) are better for hair health?

Soft water is better for hair health. Hard water can leave mineral residue on the scalp and hair shafts, causing buildup. Hard water can also cause hairfall, breakage, and dullness, depending on how hard the water is and which minerals are present in it.

How to test if your water hardness is causing hair problems?

If you have hard water in your home, you will see white chalk-like deposits on your faucets, taps, and even buckets. If you use this water to wash your hair, your hair will show signs of damage. If your hair feels rough, dry, or straw-like, you notice excessive tangles, or more breakage than usual, these are all signs of hard water damage.

What ingredients in water damage your hair and cause thinning?

Most hard water contains calcium or magnesium, which can deposit on your scalp, stopping proper absorption of the products you apply. These can cause dryness and dullness in your hair.

However, water containing chlorine or fluoride can have much worse effects on your hair. In some places, you might even get water containing lead, arsenic, and zinc, which can cause severe hair loss, greying, and scalp issues.

How long-term use of hard water affect hair density?

If you have been using hard water for a long time, you might experience hair thinning, loss of density, and widening hair partition. It can also cause scalp issues and premature balding in some cases.

Does hard water affect hair dye, texture, and strength?

Yes, hard water affects hair dye. It can fade hair dye faster and make hair feel rough, dry, and unmanageable.

Can hard water weaken hair shaft and cause split ends?

Yes, hard water can weaken hair shaft and cause split ends. Hard water contains minerals and even heavy metals that can create a film on the hair and scalp, which weighs hair down, blocks moisture absorption, and makes hair dry and brittle, which leads to split ends.

How to protect hair from hard water?

If you get hard water in your region, you can install a water-softening showerhead in your washroom. You can also use ACV rinse twice or thrice a month to remove the mineral build-up. Oiling your hair before washing can also protect your hair from hard water.
