What hard water does to hair
This is where minerals start to matter: a coating builds on the strand over successive washes, bringing dullness, tangles and faster colour fade. Chelating (detox) washes move from optional to part of the routine.
The washing routine for Tak
Make a chelating (detox) wash part of the rhythm, roughly every fourth wash, and use a gentle everyday shampoo in between. Condition well after each wash, as minerals roughen the cuticle, and expect colour-treated hair to fade faster than at home.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): April is the warmest month, averaging 38°C by day, and humidity peaks in October at about 85% on average. Day to night swings reach 14°C, which dries hair out between washes; the plan adds moisture and a sealing leave-in when a stop spans those months. 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.
Local note: treated hardness ranged 68-200 mg/L across 2013-2014 sampling.
