We’ve all heard the saying, “You can’t judge a book by its cover.” But what about judging a person by their hair? It seems like we do it all the time. And if you’re someone who’s been losing your hair, you know that people are quick to jump to conclusions. They might say you’re getting old or just not taking care of yourself. But have you ever stopped to think about whether or not your water could be causing your hair loss?

There’s a lot of debate over whether or not hard water causes hair loss. Some people swear that it’s the cause of their thinning hair, while others say that there’s no evidence to support this claim. So, what’s the truth? Does hard water cause hair loss? Or is this just another myth?

Believe it or not, hard water could be one of the culprits behind your thinning locks.

In this post, we’ll look at the evidence and see if there’s any truth to the claim. If you’re concerned about the effects of hard water on your hair, read on to learn more about this potential connection and what you can do to protect your locks.


What is Hard Water?

Hard water is water with a high mineral concentration. Water hardness is caused by high level of calcium, magnesium bicarbonates, carbonates, sulfates, iron, chloride, copper, and zinc in groundwater. Water hardness can be either transient or permanent. Temporary hardness can be easily eliminated by boiling, while persistent hardness necessitates a multistep process.

Though calcium and magnesium-rich hard water is not considered a health hazard, it impacts your hair’s health. Chloride, iron, copper, silica, lead, manganese, and cadmium are common contaminants in groundwater near industrial and coastal areas. These minerals harm your scalp and hair, resulting in hair loss.


What Is The Effect Of Hard Water On Your Hair?

Washing your hair with hard water, including toxic minerals, regularly destroys and weakens healthy hair. According to health experts, excessive amounts of minerals can harm your hair and skin.

Hard water creates mineral build-up on the scalp, preventing nutrients and moisture from reaching the hair follicles. Your hair will become malnourished and seem dull as a result of this. Calcium build-up can cause your hair to dry out and block your follicles.

A follicular block prevents healthy hair growth by interfering with the natural hair growth process. Calcium and magnesium attach to the hair shaft and weigh it down, making styling your hair more difficult. Exposure to salt or chloride dries out your hair shafts, making it brittle and prone to breakage. Frizz, split ends, discoloration, dandruff, and gradual hair thinning result if this is not addressed on time.


What Are The Signs Of Hair Damage Caused By Hard Water?

Washing your hair with hard water daily can damage your hair and scalp. The following are some of the most prevalent indications of hard water damage.

  1. Hair that is dry, frizzy, and lifeless, with the possibility of split ends.
  2. Mineral build-up causes a dry, itchy scalp.
  3. Hair that is difficult to style because it is limp and weighed down.
  4. Hair thinning over time owing to hair follicle obstruction.
  5. Strands that are frail, discolored, and prone to knots and breakage.


How To Prevent Hair Damage Caused by Hard Water?

If you suspect that hard water is causing your hair loss, you can do a few things to prevent further damage.

Install A Water Softener

If you live in an area with hard water, you might consider installing a water softener in your home. One of the best ways to protect your hair from hard water damage is to install a water softener. This will help remove the amount of calcium and magnesium in your water, making it easier for your hair to absorb moisture and nutrients.

Use A Shower Filter

If you don’t want to install a whole-house water softener, you can use a shower filter instead. A shower filter will attach to your shower head and remove the minerals from your water as it comes out. This is a great way to get soft water without making any significant changes to your plumbing.

Use A Hair Mask

If you’re already experiencing some of the adverse effects of hard water on your hair, you can try using a hair mask once a week. A hair mask will help moisturize and nourish your hair, helping to reverse some of the damage done.

Use an Apple Cider Vinegar Hair Rinse

An apple cider vinegar rinse is a great way to counteract the effects of hard water on your hair. Apple cider vinegar helps to restore the pH balance of your scalp, and it also helps to remove any build-up that the hard water may have caused.

Use A Clarifying Shampoo

If you’re experiencing a lot of build-up on your scalp, you may want to try using a clarifying shampoo once a week. A clarifying shampoo will help to remove any unwanted minerals from your hair, leaving it healthy and shiny.



Although calcium and magnesium-rich hard water are not thought to be harmful to one’s health, it does have an impact on the health of one’s hair. These minerals harm your scalp and hair, causing them to fall out.
