🧴 How Overland Park's Water Affects Your Skin, Hair & Health
When you shower, contaminants in the water don't just wash off — they're absorbed through your skin and inhaled as steam. Here's how Overland Park's water quality may be affecting you:
🧖 Skin Effects
- Dry, itchy skin due to chloramine and hard water minerals stripping natural oils.
- Exacerbation of eczema and other skin sensitivities from irritants and mineral residue.
- Premature skin aging and dullness from chlorine exposure.
- Soap scum residue left on skin, potentially clogging pores.
💇 Hair Effects
- Dry, brittle, and frizzy hair from hard water minerals and chlorine.
- Fading of color-treated hair due to oxidative damage from disinfectants.
- Dullness and lack of shine caused by mineral buildup.
- Increased hair breakage and tangling.
🫁 Respiratory Effects
- Irritation of nasal passages and lungs from inhaling vaporized chloramines and disinfection byproducts (TTHMs, HAA5).
- Potential aggravation of asthma and allergies due to steam-borne irritants.
- Dryness and discomfort in the respiratory tract.
- Increased exposure to volatile organic compounds through inhalation during prolonged hot showers.
✅ What You Can Do About It
Test Your Water Regularly
A home water test kit can provide a precise snapshot of specific contaminants in your shower water, including hardness and chlorine levels, helping you tailor your solutions.
Install a Quality Shower Filter
A good shower filter can significantly reduce chlorine, chloramines, heavy metals, and other contaminants, leading to softer skin, healthier hair, and cleaner air.
Shorten Shower Times and Use Cooler Water
Reducing exposure time and lowering water temperature can minimize the amount of contaminants absorbed through skin and inhaled from steam.
Improve Bathroom Ventilation
Using an exhaust fan or opening a window helps to dissipate steam and airborne contaminants, reducing inhalation exposure during and after showering.
Moisturize Immediately After Showering
Applying a rich moisturizer to damp skin helps to lock in hydration and counteract the drying effects of hard water and chlorine.

Is Overland Park tap water safe to shower in?
While Overland Park's tap water meets all EPA drinking water standards, it contains disinfectants like chloramine and associated byproducts, along with hardness minerals. These elements, though safe for ingestion, can cause adverse effects on skin, hair, and respiratory health when exposed to them in a hot shower environment.
Why does my skin feel dry and itchy after showering in Overland Park?
The primary culprits are chloramines, which strip natural oils from your skin, and hard water minerals (like calcium and magnesium). These minerals prevent soap from rinsing completely, leaving a residue that can clog pores and exacerbate dryness and itchiness, especially for those with sensitive skin or eczema.
Does Overland Park water damage hair?
Yes, the hard water in Overland Park can damage hair by causing mineral buildup that makes it dull, brittle, and difficult to manage. Additionally, chloramines can strip hair of its natural oils and color, leading to dryness, frizz, and premature fading for color-treated hair.
What is the chlorine smell I sometimes notice in my shower?
That 'chlorine' smell is actually due to chloramines, the disinfectant used by WaterOne. While essential for killing harmful bacteria, chloramines can become volatile in hot shower steam, releasing that distinct odor and contributing to respiratory irritation and skin dryness.
Are shower filters really effective for Overland Park water?
Yes, a good quality shower filter can be highly effective. It can significantly reduce chloramines, chlorine, disinfection byproducts (like TTHMs), and even some heavy metals, leading to noticeable improvements in skin hydration, hair health, and a reduction in respiratory irritation from steam.
