- Fading of color-treated hair due to chlorine/chloramine
- Dullness and lack of shine from mineral buildup (hard water)
- Scalp irritation and flakiness
🫁 Respiratory Effects
- Inhalation of chloramine and disinfection byproducts (DBPs) in steam
- Aggravation of asthma and other respiratory sensitivities
- Sinus irritation from chemical vapors
- Potential long-term respiratory issues from chronic DBP inhalation
✅ What You Can Do About It
Test Your Shower Water
Consider getting a home water test kit to understand the specific contaminant levels in your household's shower water, as levels can vary by location and plumbing.
Install a Shower Filter
A quality shower filter can significantly reduce chlorine, chloramine, heavy metals, and other contaminants, leading to noticeable improvements in skin and hair health.
Reduce Shower Time and Temperature
Shorter, cooler showers can minimize exposure to volatile contaminants that off-gas into steam and reduce skin absorption.
Moisturize Immediately After Showering
Applying a high-quality moisturizer to damp skin within minutes of showering helps lock in hydration and counter the drying effects of tap water.
Consider a Whole-House Filter
For comprehensive protection against contaminants throughout your entire home, a whole-house filtration system provides the ultimate solution for all water uses.

Is Lexington tap water safe to shower in?
While Lexington's tap water meets federal drinking water standards, showering introduces unique exposure routes. Hot water vaporizes chemicals like chloramine and disinfection byproducts, which can then be inhaled or absorbed through the skin, potentially leading to skin, hair, and respiratory issues.
Why does my skin feel dry and itchy after showering in Lexington?
Lexington's water contains chloramine for disinfection, and it is also moderately hard. These factors can strip natural oils from your skin, leading to dryness, itchiness, and irritation, especially for individuals with sensitive skin or conditions like eczema.
Will a shower filter help with hard water issues in Lexington?
Many shower filters are designed to reduce chlorine and other chemical contaminants. While some advanced filters may offer minor hardness reduction, a dedicated water softener is typically needed to effectively address hard water minerals like calcium and magnesium, which cause scale buildup and contribute to dry skin/hair.
What is the 'chlorine smell' I sometimes notice in my shower?
The 'chlorine smell' you detect is likely due to chloramine, the disinfectant used in Lexington's water. When heated in the shower, chloramine can off-gas, creating a noticeable odor and forming disinfection byproducts that are volatile and can be inhaled.
How do I know if my home's pipes are adding contaminants like lead?
Lead typically enters water from old lead service lines, lead pipes, or lead-based solder in household plumbing. The only way to definitively know if lead is present in your tap water is to have your water tested by a certified laboratory, especially if your home was built before 1986.
