✅ What You Can Do About It
Test Your Home's Water
Understanding the specific contaminants and hardness levels in your home's water provides personalized insights beyond general city reports, allowing for targeted solutions.
Install a Quality Shower Filter
A high-quality shower filter can significantly reduce chlorine/chloramine, heavy metals, and other contaminants, leading to noticeable improvements in skin and hair health.
Take Shorter, Cooler Showers
Minimizing exposure time and using cooler water reduces the amount of chemicals absorbed through skin and inhaled from steam, lessening potential impacts.
Moisturize Immediately After Showering
Applying a good moisturizer to damp skin helps lock in hydration and creates a protective barrier against environmental stressors, counteracting drying effects.
Consider a Whole-House Filter

Is Cary tap water safe to shower in?
While Cary's tap water meets federal drinking water standards, it contains disinfectants like chloramine and disinfection byproducts that can impact sensitive skin, hair, and respiratory health during showering. Many residents find that addressing these specific components improves their shower experience and well-being.
Why does my skin feel dry and itchy after showering in Cary?
The presence of chloramine and hard water minerals in Cary's water can strip natural oils from your skin, leading to dryness and irritation. These elements can also exacerbate conditions like eczema, leaving skin feeling tight and itchy post-shower.
Will a shower filter help with the chlorine smell and my hair issues?
Yes, a good shower filter is designed to reduce chloramine, which is often responsible for the chemical smell in shower water. By removing these harsh chemicals and potentially some minerals, filters can significantly improve hair texture, reduce dryness, and help maintain hair color.
Is Cary's water considered hard water?
Cary's water typically ranges from moderately soft to moderately hard, often around 75 mg/L (or 4.4 grains per gallon) of hardness. While not extremely hard, this level can still contribute to mineral buildup, soap scum, and dryness for those with sensitive skin and hair.
Are disinfection byproducts a concern in shower water?
Absolutely. Disinfection byproducts like TTHMs and HAAs readily volatilize into the air with hot shower steam, meaning you can inhale them directly into your lungs. They can also be absorbed through the skin, increasing your overall exposure during a shower.
