What moderate water does to hair
Neither the easy rinse of soft water nor the coating of hard: routines travel well here. The only adjustment worth making is a clarifying wash every so often to lift the light build-up.
The washing routine for Buenos Aires
Wash as usual, and make every eighth wash or so a detox (chelating) one. That single habit covers moderate water; the rest of your products and timing can stay exactly as they are.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): January is the warmest month, averaging 28°C by day, and humidity peaks in June at about 80% 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. In the humid months, frizz is the main event; anti-humidity styling matters more than wash frequency.
