Why Tap Water Damages Your Hair and Skin

What your shower water actually contains

Most city tap water is treated with chlorine to kill bacteria — a public health necessity. But in your shower, that chlorine becomes an aggressor for skin and hair.

Add limescale (calcium and magnesium carbonate) — present in 60%+ of European cities — plus traces of heavy metals from old pipes.

How chlorine damages your skin

Chlorine is an oxidant that destroys the hydrolipidic film — the thin oil-water layer protecting your skin.

• Dry, tight skin: without the protective film, moisture evaporates faster after showering
• Eczema aggravated: chlorine triggers or worsens flare-ups in sensitive individuals
• Dilated pores: chronic irritation causes mild inflammation that enlarges pores
• Premature ageing: oxidative stress from chlorine accelerates collagen breakdown

A study in the Journal of Dermatological Science (2019) confirmed that regular chlorine exposure significantly reduces skin lipid content.

What limescale does to your hair

Limescale deposits on the hair fibre with every wash, lifting the keratin cuticle — making hair rough, dull and brittle.

• Dull hair: lifted cuticles reflect light poorly
• Brittle hair: mineral deposits weaken hair structure internally
• Colour fades faster: limescale reacts with dye pigments — hairdressers estimate 30–40% shorter colour lifespan
• Itchy scalp: residue blocks follicles and irritates the scalp

Why your expensive products are less effective

Hard water reduces the efficacy of your conditioners and serums. Calcium and magnesium ions compete with active ingredients, preventing them from penetrating the hair fibre.

The solution: filter at source

The Limpéa filtered shower head uses an activated carbon cartridge removing up to 97% of chlorine and significantly reducing limescale. Results typically visible within the first week.

• Installs in 20 seconds, no plumber needed
• Filters at the point of use
• Costs a fraction of water softeners
