You've heard that pool water damages hair. You know not to swim in a chlorinated pool with freshly colored hair. But here's what most Columbus & Central Ohio women don't realize: your shower water contains chlorine too — and you're bathing in it every single day.

Columbus Division of Water chlorinates the city water supply to kill bacteria and make it safe to drink. That's a good thing for public health. But chlorine doesn't stop being an oxidizer just because it's coming out of your showerhead instead of a pool. It hits your hair and skin with the same chemistry — just at lower concentrations, over a longer cumulative exposure.

Here's what's actually happening, and what you can do about it.

The Safe Drinking Water Act requires public water systems to maintain a disinfectant residual throughout the distribution system — meaning chlorine must still be detectable at your tap, not just at the treatment plant.

Columbus uses chloramines (a combination of chlorine and ammonia) as its primary residual disinfectant. Chloramines are more stable than free chlorine and persist longer in the distribution system, which is why Columbus uses them.

For your hair and skin, chloramines behave similarly to free chlorine — they're oxidizing agents that react with organic compounds, including the proteins and lipids in your hair and skin.

This is the one that costs real money. Chlorine is an oxidizer, and hair dye molecules are organic compounds. When chlorine contacts color-treated hair, it oxidizes the dye molecules, breaking them down and causing them to fade.

The effect is most dramatic on:

• Blonde and highlighted hair — chlorine reacts with the melanin remnants in lightened hair, producing a brassy, orange, or greenish tint (the green tint is actually from copper in the water reacting with chlorine, not chlorine alone)
• Vivid colors — red, purple, and blue dyes are particularly vulnerable to oxidative fading
• Toner — the violet and blue toners used to neutralize brassiness in blonde hair are especially fragile; chlorine can strip a fresh toner in 3–5 washes

If you're spending $150–$300 at the salon every 6–8 weeks because your color fades so fast, chlorine in your shower water is a major contributing factor.

Hair is made primarily of keratin — a fibrous protein. Chlorine oxidizes the disulfide bonds in keratin, weakening the hair's structural integrity. Over time, this produces:

• Increased porosity (hair absorbs and loses moisture unevenly)
• Brittleness and breakage
• Split ends that travel up the shaft
• A rough, straw-like texture even on freshly washed hair
• Reduced elasticity (hair that snaps instead of stretching when pulled)

This is the same chemistry that happens when hair is chemically processed (bleached, permed, relaxed) — chlorine just does it more slowly, over months and years of daily exposure.

Your scalp produces sebum — natural oils that protect the hair shaft and keep it moisturized. Chlorine strips these oils, leaving hair dry from root to tip. The scalp compensates by producing more oil, which can lead to:

• Greasy roots with dry, brittle ends
• Increased scalp sensitivity or dandruff
• The need to wash hair more frequently (which means more chlorine exposure — a vicious cycle)

Chlorine raises the hair's pH and lifts the cuticle (the outer protective layer). Raised cuticles mean:

• Light scatters instead of reflecting — dull, flat appearance
• Moisture escapes faster — dry, frizzy hair
• Increased friction between strands — more tangling and breakage

Combined with Columbus hard water (which also raises hair pH and lifts cuticles), the effect is compounded. Most Columbus & Central Ohio women are dealing with both chlorine damage and hard water damage simultaneously.

Your skin's outermost layer is protected by a thin film of natural oils, ceramides, and fatty acids — the skin barrier. This barrier keeps moisture in and irritants out.

Chlorine disrupts this barrier by oxidizing the lipids that hold it together. The result is:

• Dry, tight skin immediately after showering
• Increased transepidermal water loss (your skin dries out faster)
• Greater sensitivity to soaps, detergents, and environmental irritants
• Accelerated appearance of fine lines (a compromised barrier ages faster)

For people with eczema, psoriasis, or rosacea, chlorine is a documented trigger. The National Eczema Association lists chlorinated water as a potential irritant, and dermatologists frequently recommend shower filters for patients with chronic skin conditions.

If your skin condition is managed but never fully resolved — if you're always dealing with some level of dryness, redness, or irritation — your shower water is worth investigating.

This is the long-term effect that gets less attention. Chlorine generates free radicals when it contacts skin — unstable molecules that damage collagen and elastin, the proteins that keep skin firm and elastic.

Daily free radical exposure from chlorinated shower water contributes to:

• Accelerated breakdown of collagen (loss of firmness)
• Fine lines and wrinkles appearing earlier
• Uneven skin tone and texture

This is a cumulative effect that builds over years. It's not something you'll notice after one shower — but over a decade of daily chlorinated showers, the difference is real.

Most Columbus city water users are dealing with two problems simultaneously:

1. Chlorine/chloramines from the disinfection process
2. Hard water (200–300 mg/L calcium and magnesium) from the limestone geology of central Ohio

These two factors compound each other. Hard water raises hair pH and lifts cuticles, making hair more vulnerable to chlorine damage. Chlorine strips the skin barrier, making skin more sensitive to the irritating effects of hard water minerals.

The combination is why so many Columbus & Central Ohio women feel like nothing they do for their hair and skin is ever quite enough — they're fighting a two-front battle every time they shower.

The most effective solution for Columbus & Central Ohio city water. A whole-house activated carbon filter removes chlorine and chloramines from every tap and shower in your home.

Activated carbon works through adsorption — chlorine molecules bond to the carbon surface and are removed from the water. A properly sized carbon filter removes 95–99% of chlorine and chloramines from your water supply.

The difference for hair and skin is significant:

• Color holds 2–4x longer between salon visits
• Hair feels softer and more manageable within the first few washes
• Skin feels less tight and dry after showering
• Eczema and sensitive skin conditions often improve noticeably

For Columbus city water, we typically recommend a whole house carbon filter paired with a water softener — the carbon handles chlorine, the softener handles hardness. Together they address both of the main factors damaging your hair and skin.

A shower filter with activated carbon or KDF media is a lower-cost starting point. It won't filter every tap in your home, but it addresses the highest-exposure point — your daily shower.

Quality shower filters run $50–$150 and replace cartridges every 6–12 months. They're a meaningful improvement over unfiltered city water, though not as comprehensive as a whole-house system.

Vitamin C (ascorbic acid) neutralizes both chlorine and chloramines on contact. Vitamin C shower filters are effective and inexpensive, though the cartridges need more frequent replacement than carbon filters.

Consider what you're currently spending to manage chlorine and hard water damage:

A whole-house carbon filter + softener for a Columbus home typically runs $2,000–$3,500 installed. At $200/month in product savings, that's a 10–18 month payback — and you get better hair and skin for the rest of the time you live in your home.

Before investing in any system, know exactly what's in your Columbus water. A professional water test measures chlorine levels, hardness, pH, and other factors — giving you a complete picture of what you're dealing with.

We offer free in-home water testing throughout the Columbus & Central Ohio area. The test takes about 20 minutes and comes with no obligation.

Call (614) 476-8711 or schedule your free water test. If chlorine and hard water are behind your hair and skin issues, we'll show you exactly what it would take to fix it — and what it would cost.

Your hair and skin deserve better than what's coming out of your tap.
