Using your BaByliss Professional Ionic Blue Hair Straightening Iron is easy. First, plug it in and set your desired temperature using the LED temperature settings. You can go up to 450°F depending on your hair type. Wait for the iron to heat up - it'll be fast thanks to the ceramic heater. Then, take small sections of your hair and slowly run the iron through from root to tip. The natural ions will help reduce frizz and give you a sleek look. When you're done, unplug the iron and let it cool down completely. Always handle the iron with care as the plates can get very hot. For maintenance, make sure to keep the plates clean. You can use a soft, dry cloth to wipe them after each use. Store the iron in a cool, dry place. Remember, it's 220v compatible but you'll need a transformer or outlet plug (not supplied). And it comes with a limited 4-year warranty, so if you have any issues, reach out to the manufacturer.
