The water
280 mg/LVery hard
Source: Israel Water Authority (gov.il) · Official figure. Hardness counts dissolved calcium and magnesium in the water; it is the number your hair meets in the shower.
What very hard water does to hair
Among the hardest water on the map: the mineral film builds fast, especially on porous, bleached or colour-treated hair, and ordinary shampoo alone will not shift it. Plan on weekly chelation and richer conditioning, more so the longer you stay.
The washing routine for Jerusalem
Chelating (detox) washes do the heavy lifting: about every second wash, with a gentle shampoo between and rich conditioning after. On a long stay, a weekly deep treatment keeps porous or bleached hair from going brittle under the build-up.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): July is the warmest month, averaging 33°C by day, and humidity peaks in January at about 73% on average. Day to night swings reach 13°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.
Local note: 2010 value in 2005 to 2010 series; rising desalinated share lowers hardness.
