This advanced styling tool is designed to provide efficient hair straightening with enhanced protection, thanks to its Keratin-infused ceramic plates. Please read this manual thoroughly before use to ensure safe and optimal performance of your device.
Safety Information
For your safety, please observe the following precautions:
- Keep away from water and flammable materials.
- Do not use on damp or wet hair.
- Allow the device to cool down before touching the plates or storing it.
- Unplug the device when not in use.
Setup
- Unpack: Carefully remove the hair straightener and all accessories from its packaging.
- Inspect: Check the device for any visible damage. Do not use if damaged.
- Placement: Place the straightener on a heat-resistant, flat surface away from water.
- Power Connection: Plug the power cord into a suitable electrical outlet. Ensure the voltage matches your local power supply.
Operating Instructions
Follow these steps for effective hair straightening:
- Preparation: Ensure your hair is clean, dry, and free of tangles. Apply a heat protectant spray if desired.
- Power On: Press and hold the power button to turn on the straightener. The digital display will illuminate.
- Select Temperature: Use the '+' and '-' buttons to adjust the temperature. The S8590 offers multiple heat settings from 160°C to 230°C. Choose a temperature appropriate for your hair type. Fine hair typically requires lower temperatures, while thicker hair may benefit from higher settings.
- Heat-Up: The straightener heats up quickly. The digital display will show the temperature increasing until it reaches your selected setting.
- Straightening: Separate a small section of hair. Place the hair between the ceramic plates, close to the roots. Gently glide the straightener down the hair section from root to tip in one smooth motion. Repeat on all sections until desired straightness is achieved.
- Curling (Optional): For curls or waves, clamp a section of hair near the roots, rotate the straightener 180 degrees, and slowly pull it through the hair, maintaining the rotation.
- Power Off: After use, press and hold the power button to turn off the device. Unplug it from the outlet.
- Cool Down: Allow the straightener to cool completely before storing.
