What very hard water does to hair
Build-up is fast, especially on porous or bleached hair. Weekly chelation and richer conditioning are worth it on long stays.
The washing routine for Deauville
Set the rhythm tight: a chelating (detox) wash every second wash, gentle shampoo in between, and rich conditioner after every wash. For long stays, a weekly deep treatment keeps bleached or porous hair from going brittle.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): July is the warmest month, averaging 22°C by day, and humidity peaks in December at about 85% 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.
