What moderate water does to hair
A forgiving middle ground: most routines work as they are, with a light mineral film building slowly over time. An occasional clarifying wash keeps shine from dulling.
The washing routine for Johannesburg
Keep your normal rhythm and slot a detox (chelating) wash in about every eighth wash to lift the light mineral film before it dulls shine. Nothing else needs to change.
Climate, from recent records (Open-Meteo, ERA5 2015-2024): January is the warmest month, averaging 26°C by day, and humidity peaks in February at about 68% on average. Day to night swings reach 15°C, which dries hair out between washes; the plan adds moisture and a sealing leave-in when a stop spans those months.
Altitude: at about 1,749 m, UV runs roughly 10 to 12% stronger per 1,000 m and the air is dry, so UV protection and moisture join the routine; the planner builds both in.
Plugs and power for your tools
Sockets: Type C, M and N. Supply: 230 V, 50 Hz.
A 120 V only dryer or styler (North American) will burn out on this supply, and a plug adapter does not change voltage. Check the label for dual voltage (100-240 V) before you plug in.
Plug, voltage and frequency: IEC World Plugs and national standards.
