5. Operation

5.1 Power On and Temperature Selection
- Plug the appliance into an electrical outlet. The LCD display will illuminate.

- Booster Mode (210 °C): For intensive straightening, suitable for thicker or more resistant hair.
- Allow approximately 30 seconds for the straightener to reach the selected temperature. The display will indicate when it is ready.
5.2 Straightening Hair
- Ensure your hair is clean, dry, and detangled.
- Divide your hair into small, manageable sections.
- Take one section of hair and place it between the ceramic plates, close to the roots.
- Gently close the plates and glide the straightener slowly and evenly down the hair section, from roots to ends. The floating plate system ensures constant contact.
- Repeat for all sections until desired straightness is achieved.
- Activate the ionic function (if desired) by pressing the ionic button to reduce static and enhance shine.
5.3 Curling Hair (Liss & Curl Function)
The 2-in-1 Liss & Curl system allows you to create beautiful curls and waves.
- Ensure your hair is clean, dry, and detangled.
- Divide your hair into small, manageable sections.
- Take one section of hair and place it between the ceramic plates, close to the roots.
- Close the plates and rotate the straightener 180 degrees away from your face.
- Slowly glide the straightener down the hair section, maintaining the rotation. The rounded edges of the plates will help form the curl.
