What's Hyun Bin's hairstyle like in their world?

Hello, I'm a hair stylist. The hairstyle you said is Korean hairstyle.

This is a natural and elegant feeling. First, the barber uses a hair dryer, and then waxes it to capture the sense of lines and facial contours. It's simple. It doesn't need ironing. The point is to blow the hair roots fluffy and lined.
