How Filtered Water Affects Skin and Hair

How Chlorine Affects Skin and Hair

Chlorine is added to municipal water as a disinfectant, but it's also a chemical irritant. When you shower, chlorine strips the natural oils (sebum) from your skin and hair. This leads to dry, itchy skin, exacerbated eczema and psoriasis, brittle hair with split ends, faded hair color (especially for dyed hair), and irritated eyes. The warm water of showers opens pores and hair cuticles, making the absorption of chlorine more significant than when drinking chlorinated water. Studies have shown that showering in chlorinated water can actually result in greater chlorine absorption than drinking it.

Hard Water and Your Body

Hard water contains high levels of calcium and magnesium. While safe to drink, these minerals cause problems for skin and hair. Hard water reacts with soap to form soap scum - a sticky film that doesn't rinse away completely. This residue clogs pores, traps bacteria, and creates a barrier that prevents moisturizers from penetrating. On hair, mineral buildup makes strands feel rough, look dull, and become more prone to tangles and breakage. Hard water also reduces shampoo lather, leading people to use more product, which compounds the residue problem.

Skin Improvements

Switching to a shower filter can produce noticeable improvements within 2-4 weeks. Users commonly report: reduced dryness and itching, less redness and irritation, improvement in eczema and psoriasis symptoms, better skin hydration (moisturizers work more effectively), reduced acne breakouts (from less pore clogging), and softer, more supple skin. People with sensitive skin see the most dramatic improvements. The American Academy of Dermatology acknowledges that water quality can significantly affect skin conditions.

Hair Improvements

Filtered shower water transforms hair health over time. Benefits include: reduced mineral buildup that weighs hair down, restored natural shine and softness, longer-lasting hair color (less fading), better lathering with less shampoo needed, less frizz and fewer tangles, and stronger, less brittle strands. Many users report they can go longer between hair washes because their scalp produces less compensatory oil. Salon professionals increasingly recommend shower filters to clients, especially those with color-treated or damaged hair.

Types of Shower Filters

The most common type uses KDF (Kinetic Degradation Fluxion) media combined with activated carbon. KDF converts chlorine into harmless chloride through a redox reaction, works well in hot water (where carbon alone is less effective), and lasts about 6-10 months. Some premium filters add vitamin C, which neutralizes both chlorine and chloramine. Others include ceramic balls for additional filtration. Prices range from $25-$60 for the unit, with replacement cartridges costing $15-$30 every 6 months.

Whole House Benefits for Bathing

While shower filters are effective, a whole house carbon filter provides benefits throughout your home. Filtered water for bathing means no chlorine absorption through skin or inhalation through steam. Your bathroom surfaces will have less soap scum buildup. Your laundry will be softer with less detergent needed. And if you fill bathtubs or sinks for soaking, that water is filtered too. The investment in whole-house filtration pays dividends beyond just drinking water.
