Source: Yorkshire Water, York North water supply zone report 2024 · Official 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 York
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 21°C by day, and humidity peaks in December at about 88% on average. In the humid months, frizz is the main event; anti-humidity styling matters more than wash frequency.
Local note: York has several supply zones; this is the York North zone mean (105.7 mg Ca/l, about 264 mg/L as CaCO3)..
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 (BS 7671 allows a full socket only 3 m or more from the bath or shower).
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.
