What soft water does to hair
Very little gets between your shampoo and your hair here: lather is easy, rinsing is clean and build-up barely features. Fine hair may go limp or flyaway, and heavy conditioning weighs it down faster.
The washing routine for Sao Paulo
Keep your normal rhythm; soft water asks for no detox routine. Go lighter on conditioner, which feels heavier in soft water, and if fine hair goes limp, reach for volume at the roots rather than more product through the lengths. A clarifying wash now and then is plenty.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): January is the warmest month, averaging 27°C by day, and humidity peaks in March at about 85% on average. In the humid months, frizz is the main event; anti-humidity styling matters more than wash frequency.
Plugs and power for your tools
Sockets: Type C and N. Supply: 127 V, 60 Hz in Sao Paulo (Brazil varies by city).
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.
