The water
140 mg/LHard
Source: Estimate, reconciled 2026-10-18 (municipal supply basis; earlier figure measured Gunung Kidul dug wells, not city tap) · Estimate figure. Hardness counts dissolved calcium and magnesium in the water; it is the number your hair meets in the shower.
What hard water does to hair
Calcium and magnesium deposit steadily at this level, roughening the cuticle so hair looks duller, tangles more and loses colour faster. A regular chelating (detox) wash is what keeps it in check.
The washing routine for Yogyakarta
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): May is the warmest month, averaging 31°C by day, and humidity peaks in February at about 88% 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.
