It moisturizes and smooths hair while styling and caring for static electricity. With advanced heating technology, it can reach a maximum temperature of 230°C in 45 seconds. Rapid heating reduces hair damage caused by temperature changes, allowing you to quickly achieve straight hair or natural styling even on busy mornings. 【16-Level Temperature Adjustment & Memory Function】 The straight brush has 16 temperature settings in 10°C increments from 80°C to 230°C. It supports a wide range of hair types, from fine and thin hair to coarse and thick hair. You can create a variety of hairstyles with a single brush, from natural straight hair to curl arrangements. In addition, it has a temperature memory function, so when you turn it on again, it automatically remembers the previous setting temperature. It's convenient for daily use as a brush iron. 【Misoperation Prevention Lock & LED Display】 The heat brush automatically activates a lock if there is no operation for 5 seconds after adjusting the temperature. The "+" and "-" button operations are disabled, and the set temperature is maintained. "LOC" is displayed on the LED screen, and to unlock, simply press the power switch twice.
