Ionic: Ionic technology helps hair dry faster, prevents frizz, and protects hair from heat compared to traditional hair dryers.
Cool air: Button or function that blows cold air instead of hot. It is used at the end of styling to “set” the hairstyle and reduce frizz.
Turbo: The Turbo function is an enhanced speed or heat setting that provides a stronger airflow for faster drying. By increasing the motor's power, it generates a more intense airflow. It is usually activated with a separate button.
Folding: (Foldable/Folding Handle): The handle folds toward the body of the device so it takes up less space in a suitcase or drawer. This is a feature mainly found in travel hair dryers.
Dual voltage: It typically works on both 110–120V and 220–240V. It is useful for international travel, as it can be used in countries with different electrical systems without a transformer (you may only need a plug adapter).
