Is Your Shower Water Affecting Your Hair and Skin?

You Think About What You Put On Your Hair. But What Are You Washing It In?

We spend a lot of time thinking about shampoos, conditioners, serums, moisturizers and skincare ingredients.

But there’s one part of the routine that’s easy to overlook: your water.

Every shower exposes your hair and skin to whatever is present in your home’s water supply. Depending on where you live, that can include chlorine or chloramine used for municipal disinfection, minerals associated with hard water, metals and other substances picked up as water travels through the distribution system and your home’s plumbing.

That doesn’t mean your tap water is unsafe. In fact, chlorine and chloramine play an important role in keeping public drinking water free of harmful microorganisms. But the water coming out of your shower can still affect the way your hair and skin look and feel.

Chlorine and Chloramine: Why Are They in Your Water?

Most public water systems disinfect drinking water before it reaches your home. Chlorine is one of the most commonly used disinfectants, while some utilities use chloramine, which is generally created by combining chlorine and ammonia.

Chloramine lasts longer in the distribution system, which is one reason utilities may choose it over chlorine. The EPA states that chloraminated water meeting regulatory standards is considered safe for drinking, bathing and other household uses.

But “safe to shower in” and “ideal for the way your hair feels after washing” aren't necessarily the same question.

That’s where filtration can become part of a personal-care routine.

What About Hard Water?

If you’ve ever stepped out of the shower feeling like your hair still has residue on it, your water hardness may be part of the equation.

Hard water contains elevated levels of dissolved minerals, particularly calcium and magnesium. These minerals can interact with soaps and shampoos and may leave deposits behind.

Research into exactly how hard water affects hair is still developing, and studies have produced mixed results. Some studies have found greater mineral deposition on hair exposed to hard water, while another found no significant change in hair tensile strength or elasticity. A separate study did find reduced hair strength after repeated exposure to hard water.

In everyday terms, people living with hard water may notice things like:

• Hair that feels coated, dull or difficult to rinse clean
• Increased product buildup
• Shampoo that doesn't lather as easily
• Hair that feels rough or less manageable
• Mineral deposits on shower doors, fixtures and tile

One important distinction: a shower filter is not the same thing as a water softener. Traditional water softeners are designed specifically to remove or exchange hardness minerals like calcium and magnesium. Shower filtration is generally designed to target other substances in the water.

That distinction is worth understanding before choosing any water treatment system.

And Your Skin?

Your skin has its own protective barrier, and what you wash it with can affect how that barrier feels.

Research has found associations between hard-water exposure, cleansing products and increased surfactant residue on the skin. One controlled study found that washing in harder water increased deposits from a common cleansing ingredient and was associated with greater skin irritation in some participants.

That doesn’t mean hard water or chlorinated water automatically causes a skin condition. The EPA also notes that properly regulated chloraminated water has no known or anticipated adverse skin effects for the general population.

Still, if your skin consistently feels tight or dry after showering, your entire routine — including the water itself — is worth considering.

Color-Treated Hair Deserves Extra Attention

When you've invested in highlights, color or other chemical treatments, you're already paying close attention to what touches your hair.

Water quality is another part of that equation.

Mineral deposits can change how hair feels and behaves, while repeated washing exposes the hair shaft to your water chemistry day after day. Using products specifically formulated for color-treated hair can help, but evaluating your shower water gives you another piece of the picture.

In other words, your shampoo may not be the only variable.

Your Shower Is One of Your Biggest Daily Water Exposures

Think about how much water passes over your body during a single shower.

Now multiply that by seven days a week.

Unlike drinking water, where you may consume a few glasses throughout the day, shower water continuously comes into contact with your hair and skin for several minutes at a time.

That's why we believe shower water deserves the same attention as the products sitting on your bathroom shelf.

Start With Your Water

If your hair feels different after moving to a new city, your skin suddenly feels drier, or your favorite products don't seem to work the way they used to, it may be worth learning more about your water.

Start by checking your local water-quality report to see which disinfectant your utility uses and what contaminants have been detected in your municipal supply.

Then choose filtration based on your actual water, rather than assuming every shower filter does the same thing.

At Santé for Health, that's why we use different filtration media designed to address different water-quality concerns rather than relying on a single filtration material.

Because better water care starts with understanding what's actually coming through your shower.
