Generally speaking, actually getting bangs will make your face smaller. The point is to make the whole hair feel like an inverted triangle. If the top of the head is wider, it will make the face smaller. If you have a square face, you can imitate the short hair of Xiao S. If you have a round face but a pointed chin, you can consider keeping long hair. It would be nice to have Hera Xinwei (I can't send a picture, alas, give Baidu a kiss). Although there is a saying that curly hair makes the face look small, what I see in reality is just the opposite. Therefore, it is recommended to keep your hair straight, cut your bangs first, and then curl it when it is long. At this time, everyone's eyes will fall below, but they will not look back.
