The water
215 mg/LVery hard
Source: City of Aspen · Official 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 Aspen
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 26°C by day, and humidity peaks in January at about 69% on average. Day to night swings reach 19°C, which dries hair out between washes; the plan adds moisture and a sealing leave-in when a stop spans those months.
Local note: City states hardness varies with the seasons.
Altitude: at about 2,404 m, UV runs roughly 10 to 12% stronger per 1,000 m and the air is dry, so UV protection and moisture join the routine; the planner builds both in.
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.
