What moderate water does to hair
A forgiving middle ground: most routines work as they are, with a light mineral film building slowly over time. An occasional clarifying wash keeps shine from dulling.
The washing routine for Saint-Jean-de-Luz
Keep your normal rhythm and slot a detox (chelating) wash in about every eighth wash to lift the light mineral film before it dulls shine. Nothing else needs to change.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): August is the warmest month, averaging 25°C by day, and humidity peaks in June at about 83% on average. In the humid months, frizz is the main event; anti-humidity styling matters more than wash frequency.
Local note: 2026 readings climb through the year, from 76-87 mg/L in winter to 141-153 mg/L in summer.
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.
