If you live in New York, NY, your tap water contains 22 detected contaminants — many of which exceed health guidelines set by the Environmental Working Group (EWG). While your water may be "legal," legal doesn't mean safe.
Every time you shower, your skin and hair absorb these chemicals through steam and direct contact. Here's exactly what's in your water and what you can do about it.

How New York's Water Affects Your Skin and Hair
You might think your tap water is only a concern when you drink it. But your skin is your largest organ, and studies show you absorb more chlorine through a 10-minute shower than drinking 8 glasses of the same water.
Here's what New York, NY water contaminants do to your body:
- Dry, itchy skin: Chlorine and chloramine strip your skin's natural oils, causing dryness, irritation, and eczema flare-ups
- Hair damage: Hard water minerals coat hair strands, making them brittle, dull, and prone to breakage and thinning
- Acne and breakouts: Chemical residues clog pores and disrupt your skin barrier, triggering inflammatory acne
- Color-treated hair fading: Chlorine is a bleaching agent — it strips hair color faster than anything else
