How New York City Water Affects Your Skin & Hair
At 20 mg/L CaCO3, New York City water has measurable effects on your skin and hair health:
- Soft water but heavy chloramine treatment dries skin and hair
- Strong chemical smell in older buildings with ageing pipes
- Scalp irritation, especially in winter with dry indoor heating
- Colour-treated hair fades faster due to chloramine oxidation
These effects are gradual but real and accumulate with every daily shower.
