What soft water does to hair
Very little gets between your shampoo and your hair here: lather is easy, rinsing is clean and build-up barely features. Fine hair may go limp or flyaway, and heavy conditioning weighs it down faster.
The washing routine for Chamonix
Keep your normal rhythm; soft water asks for no detox routine. Go lighter on conditioner, which feels heavier in soft water, and if fine hair goes limp, reach for volume at the roots rather than more product through the lengths. A clarifying wash now and then is plenty.
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 77% on average.
Local note: Main town network is very soft (25-47 in 18 of 21 readings); 3 readings at 113-116 suggest an occasional harder backup supply.
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.
