What hard water does to hair
Hair washed here picks up a mineral film that flattens shine and makes lengths catch and knot. Colour-treated hair shows it first. Chelating (detox) washes belong in the rhythm, not as an occasional rescue.
The washing routine for Prague
Plan on a chelating (detox) wash every fourth wash or so, gentle shampoo for the washes between, and thorough conditioning each time. The rhythm, kept up, prevents the dullness and tangling this water otherwise causes.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): July is the warmest month, averaging 26°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.
Plugs and power for your tools
Sockets: Type C and E. Supply: 230 V, 50 Hz.
Full sockets by the sink are standard (kept outside the 60 cm splash zones around the bath and shower, and RCD protected, under the IEC 60364 zone rules).
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.
