What very hard water does to hair
Build-up arrives quickly at this level: minerals coat the strand wash after wash, and porous or bleached hair suffers most, going rough, dull and brittle. Weekly chelation and richer conditioning are worth it on long stays.
The washing routine for Scottsdale
Chelating (detox) washes do the heavy lifting here: about every second wash, with a gentle shampoo between and rich conditioning afterwards. On a long stay, add a weekly deep treatment so porous or bleached hair does not turn brittle under the build-up.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): June is the warmest month, averaging 41°C by day, and humidity peaks in January at about 54% on average. Day to night swings reach 16°C, which dries hair out between washes; the plan adds moisture and a sealing leave-in when a stop spans those months. In the hot months, sun and sweat do as much damage as the water: shade, a hat and a rinse after swimming carry the routine.
Plugs and power for your tools
Sockets: Type A and B. Supply: 120 V, 60 Hz.
Full sockets by the sink are standard (the National Electrical Code requires one within 3 feet of each basin, GFCI protected).
A dryer or styler wound for 230 V only will run weak on this supply, and a plug adapter does not change voltage. Check the label for dual voltage (100-240 V) before you travel.
Plug, voltage and frequency: IEC World Plugs and national standards.
