Are you noticing that your hair is looking and feeling dry, brittle, and unmanageable? Chances are it's due to hard water. Hard water is a common issue for many people living in certain areas of the country whose water supply contains high levels of minerals like calcium and magnesium. These minerals can be damaging to the hair over time as they prevent moisture from properly absorbing into strands leading to dryness, breakage, frizziness, split ends and more.

But don't worry - there are things you can do to fix it! In this article we'll discuss what hard water does to your hair and how you can protect yourself against its effects so that you're left with healthy-looking locks every day.

What Exactly Is Hard Water?


Hard water is a term used to describe water that has high levels of minerals such as calcium and magnesium in it, which makes it hard for the body to absorb. These minerals can come from a variety of sources, including soil, rock, vegetation, and industrial contaminants. Hard water is generally more alkaline than soft water and has a higher pH level, which can lead to build up of minerals on the scalp and hair shaft.

The minerals found in hard water are unable to penetrate deeply into the cuticle layer of your hair strands, making it difficult for moisturizing ingredients to be absorbed as well. This leads to dryness, frizziness, split ends, breakage and other signs of damage. In addition, hard water can also cause a buildup on the scalp that makes it difficult for hair to grow properly.

Don't Worry! Prevention and Solutions for Hair Damage from Hard Water

Invest in a Shower Filter to Reduce Hard Water Effects

Investing in a shower filter is key to reducing the negative effects of hard water on your hair. Shower filters are designed to remove minerals and other impurities from tap water, making it softer and more suitable for your hair. This can help reduce dryness, frizziness, split ends, and other signs of damage associated with hard water exposure.

Make Sure Your Hair is Cleaned With Products That Are Specially Formulated for Hard Water

It is important to ensure that your hair is thoroughly cleaned with products that are specifically designed to counteract the effects of hard water. Shampoos and conditioners that are formulated for hard water will help reduce buildup, allowing the moisturizing ingredients in the product to penetrate deeper into the hair shaft. These products contain chelating agents, which help to bind and remove minerals from the hair, as well as humectants that attract moisture and make it easier for your strands to absorb.

Use a Clarifying Shampoo or Vinegar Rinse to Remove Residue from Hard Water

Clarifying shampoos and vinegar rinses are great for removing residue that has built up on your hair due to hard water exposure. Clarifying shampoos contain strong surfactants that help remove dirt, dead skin cells, and product buildup from the scalp and hair. The surfactants also help break down the mineral deposits, making it easier to rinse them away. A vinegar rinse can also help remove minerals and other impurities from the hair, as well as restore the hair’s natural pH balance.

Condition Your Hair Regularly to Combat Damaged Hair Cuticles

Conditioning your hair is one of the best ways to combat damage caused by hard water. Conditioners help to replenish moisture and nutrients in the cuticles, restoring them to a healthy state. The cuticles are the protective outer layer of your hair strands, and when they become damaged due to hard water exposure, it can lead to dryness, frizziness, and breakage. Using a conditioner regularly will help to keep your hair looking and feeling healthy. We suggest using a conditioner on the bottom half of you hair (from your ears down) every time you wash you hair to prevent dryness and frizzy hair.

Deep-Condition Your Hair Once a Week for Extra Repair and Protection

Deep-conditioning your hair once a week is an effective way to repair damage caused by hard water and protect it from further damage. Deep-conditioning treatments provide extra nourishment and moisture to the hair, helping to replace lost nutrients and minerals caused by hard water exposure. These treatments also help to strengthen the cuticles of the hair strands, making them more resistant to environmental damage and breakage.

Protect Your Hair from the Sun’s Rays

Finally, it is important to protect your hair from the sun's damaging rays by wearing a hat or scarf when outdoors. The sun can cause more damage to hair that is already weakened from hard water exposure, leading to further dryness and breakage. Wearing a hat or scarf when outdoors will help reduce the amount of direct sunlight your hair is exposed to, helping to keep it looking healthy and strong.
