The water
237 mg/LVery hard
Source: City of Phoenix (via TapWaterData) · Published figure. Hardness counts dissolved calcium and magnesium in the water; it is the number your hair meets in the shower.
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 Phoenix
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 42°C by day, and humidity peaks in January at about 55% 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.
Local note: Blend of Colorado River (CAP) and Salt River water with groundwater varies hardness.
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.
