Source: Ministere de la Sante, SISE-Eaux via Hub'Eau API (reseau all La Clusaz networks pooled) · Official figure. Hardness counts dissolved calcium and magnesium in the water; it is the number your hair meets in the shower.
What hard water does to hair
Calcium and magnesium deposit steadily at this level, roughening the cuticle so hair looks duller, tangles more and loses colour faster. A regular chelating (detox) wash is what keeps it in check.
The washing routine for La Clusaz
Build a chelating (detox) wash into the rhythm, about every fourth wash, with a gentle everyday shampoo between detox days. Condition well after each wash; minerals roughen the cuticle, and colour-treated hair fades faster here.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): July is the warmest month, averaging 23°C by day, and humidity peaks in May at about 81% on average. In the humid months, frizz is the main event; anti-humidity styling matters more than wash frequency.
Local note: Village networks run 112-170; the La Graillere-Le Fernuy sector is softer (47-60).
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.
