What soft water does to hair
Expect easy lather and a clean rinse, with almost no mineral coating wash to wash. The common complaint in soft water is the opposite of damage: hair that feels too soft, flat at the roots and quick to fly away.
The washing routine for Maui (Kahului)
No special rhythm is needed. Keep your usual shampoo and spacing, lighten the conditioner if hair feels coated, and save the clarifying wash for the odd occasion rather than a schedule.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): July is the warmest month, averaging 30°C by day, and humidity peaks in January at about 72% on average. 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.
