What very hard water does to hair
Expect rapid build-up: hair turns rough and dull, tangles at the ends and fades in colour as the coating thickens. Frequent chelating (detox) washes and deep conditioning are the standing routine here, particularly for bleached or porous hair.
The washing routine for Tucson
Treat detox as the default: a chelating (detox) wash every second wash, a gentle formula on the days between, and never skip conditioner. Add a weekly deep treatment on longer stays to protect porous or bleached hair from the rapid build-up.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): June is the warmest month, averaging 38°C by day, and humidity peaks in January at about 53% 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: Hardness rises as the share of CAP Colorado River water blended with local groundwater increases.
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.
