7 Best Ways to Protect Your Hair from Hard Water

How is your hair affected by hard water? How can hard water damage your hair? People all over the world struggle with hair loss.

What is Hard Water and Its Effects on Hair?

Minerals are present in any type of water. However, there are too many of them in hard water. According to researchers, soft water only has 10 ppm of CaCO3 but hard water has 212.5 ppm.

Moreover, hard water makes it difficult for soap or shampoo to lather. Soap combines with the bicarbonates, chlorides, and sulfates of calcium and magnesium to form salt precipitates.

These can lead to the below hair problems:

  • Dull Hair: Your hair may appear dull due to these mineral deposits. They reduce hair shine by being trapped in the hair shaft.
  • Rough and Frizzy Hair: Mineral deposits may cause your hair to become rough and frizzy hair.
  • Greasy Hair: The excessive mineral deposits that stick to your hair strands will make your hair feel greasy and unclean.
  • Split Ends: The mineral deposit on the scalp and the hair shaft can also cause split ends.
  • Clogged Pores: Clogged pores are caused by the minerals that are deposited on the scalp. The natural sebum may also be blocked by them. Your hair begins to appear dry and lifeless as a result. Additionally, dandruff, scalp sensitivity, and scalp infections are caused by mineral deposits on the scalp.

Does Hard Water Cause Hair Fall?

Does Hard Water Cause Hair Fall

Hard water contains too much calcium and magnesium which combines with your hair products to produce salt. 

Your scalp and hair are left with a salty residue that stops your scalp from absorbing the moisturizer from the conditioner.

Your hair becomes dry and matted as a result, which causes breakage. Uncontrolled hair breakage might result in thinning hair. The following are some ways that hard water might damage your hair:

  • Calcium deposits stop the scalp from absorbing moisture.
  • Your scalp develops mineral crystals that cause brittle hair.
  • Hard water minerals make soap and shampoo ineffective.
  • Excessive mineral buildup obstructs your scalp’s pores.
  • Causes frizzy hair
  • Hair lacks volume and is always flat and frizzy.
  • Mineral deposit promotes the development of germs, infections, and yeast.
  • causes dandruff by making the scalp dry

Best Ways to Protect Your Hair from Hard Water

If you’re trying to restore life to damaged hair, the below techniques should work well.

1. Install a Water Softening System

The calcium and magnesium ions in hard water are replaced out for sodium ions by a water softening system. Install a water softener so you can wash your hair with tap water straight from the tap. 

2. Use a Shower Filter

Use a Shower Filter to Protect Your Hair from Hard Water

A shower filter enhances the quality of the water by removing the extra minerals in the water. Moreover, it reduces water hardness.

It is a reasonably priced device that can be cleaned by detaching it from the shower head. Every six months, change the filter.

3. Use A Chelating Shampoo

Chelating shampoos help in getting rid of any dirt, mineral buildup, and product buildup.

If you reside in an area with hard water, It is usually a good idea to use a chelating shampoo rather than a regular one to remove mineral buildup.

Additionally, chelating shampoos keep your hair and scalp clean, light, and breathable.

4. Apply a Hair Mask

To maintain your hair healthy, apply a deep conditioning hair mask once a week. Avocado can be used as a hair mask, as can a mixture of coconut and rosehip oils.

Apply the mask on the hair follicles and scalp. After 45 minutes, remove the mask with a chelating shampoo (or use a shower filter if you want to use a mild shampoo).

5. Lemon Rinse

6. Apple Cider Vinegar Rinse

Rinsing with apple cider vinegar also helps in lowering mineral buildup. Your hair will become healthy, soft, and shiny due to apple cider vinegar wash helps in balancing the hair sebum secretion. 

You can combine one mug of water and one teaspoon of apple cider vinegar. Use it to rinse your hair to get rid of the mineral buildup.

Make sure to rinse off the solution with warm water rather than cold.

You can also use bottled water that has been purified to avoid damage to your hair. Many people purchase bottled water for the purpose of cleaning their hair and protecting it from damage.
