5. Operating Instructions
The DryWave Nebúla offers various settings to customize your drying experience for optimal curl definition and care.
- Power On/Off: Press the power button (O) located at the bottom of the handle to turn the appliance on or off.
- Select Speed: Use the speed control button (|||) to choose from 3 different airflow speeds. Adjust according to your hair type and desired drying intensity.
- Adjust Temperature: Use the temperature control button (°C) to select from 3 temperature settings. A cold shot function (*) is also available to set your style.
- Activate Plasma Function: Press the Plasma Function button (~) to activate the anti-frizz technology. This helps eliminate static electricity, leaving curls shiny and disciplined.
- Soft Mode: For more delicate curls or to seal the shape after styling, activate the Soft mode. Refer to the specific button on the control panel for this function.
