Source: Uisce Eireann · Published figure. Hardness counts dissolved calcium and magnesium in the water; it is the number your hair meets in the shower.
What very hard water does to hair
Expect rapid build-up: hair turns rough and dull, tangles at the ends and fades in colour as the coating thickens. Frequent chelating (detox) washes and deep conditioning are the standing routine here, particularly for bleached or porous hair.
The washing routine for Dublin
Treat detox as the default: a chelating (detox) wash every second wash, a gentle formula on the days between, and never skip conditioner. Add a weekly deep treatment on longer stays to protect porous or bleached hair from the rapid build-up.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): July is the warmest month, averaging 19°C by day, and humidity peaks in November at about 84% on average. In the humid months, frizz is the main event; anti-humidity styling matters more than wash frequency.
Local note: Varies sharply by supply zone, from about 50 mg/L on the Ballymore Eustace side to 323 mg/L on the Leixlip side.
Plugs and power for your tools
Sockets: Type G. Supply: 230 V, 50 Hz.
Sockets are not permitted in bathrooms, expect a shaver point only (Ireland’s wiring rules ban general purpose outlets in bathrooms and wet areas; shaver sockets are the exception).
A 120 V only dryer or styler (North American) will burn out on this supply, and a plug adapter does not change voltage. Check the label for dual voltage (100-240 V) before you plug in.
Plug, voltage and frequency: IEC World Plugs and national standards.
