See-through bangs are thin, wispy bangs that show a bit of your forehead. They are often worn a bit longer at the sides to give your fringe a layered shape. Unlike the blunt bangs, see-through bangs work at giving you a softer look because they are less dense. This type of fringe frames your face without covering your forehead entirely, allowing you to "see through" it. It also looks lighter and more laidback.
It is often seen these days on various Korean hairstyles.
