The comfortable middle. Most routines work unchanged; a clarifying wash now and then keeps shine.
The washing routine for Nakhon Sawan
Your usual routine holds here, with one addition: a chelating (detox) wash roughly every eighth wash keeps the gentle build-up from accumulating. Condition as normal after every wash.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): April is the warmest month, averaging 37°C by day, and humidity peaks in September at about 84% 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.
