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 Los Angeles
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): August is the warmest month, averaging 32°C by day, and humidity peaks in May at about 67% on average. Day to night swings reach 14°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.
