What hard water does to hair
Minerals start to coat the strand: dullness, tangling, colour fade. Chelating (detox) washes enter the routine.
The washing routine for Mexico City
Build a chelating (detox) wash into the rhythm, about every fourth wash, with a gentle everyday shampoo between detox days. Condition well after each wash; minerals roughen the cuticle, and colour-treated hair fades faster here.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): April is the warmest month, averaging 27°C by day, and humidity peaks in September at about 77% 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.
Altitude: at about 2,238 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: 127 V, 60 Hz.
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.
