What soft water does to hair
Lathers easily, rinses clean. Can leave fine hair limp and flyaway; conditioners feel heavier.
The washing routine for Tromso
Wash as you would at home in soft water: there is no mineral load to manage. Go easy on rich conditioners, which can weigh hair down here, and reach for volume at the roots if fine hair sits flat.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): July is the warmest month, averaging 17°C by day, and humidity peaks in October at about 90% 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 F. 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.
