고데기 is a popular hair styling tool used to create curls or waves in hair. It typically consists of a heated barrel that can be made from various materials, such as ceramic or titanium, which helps to evenly distribute heat and reduce damage to the hair. Users wrap sections of their hair around the barrel, allowing the heat to set the style. Many people use 고데기 for special occasions or daily styling, as it offers versatility in achieving different looks. It is often paired with hair products like heat protectants to minimize damage. Proper usage and technique can lead to long-lasting and beautiful hairstyles.
