Don't straighten your bangs, or you will highlight your long face. If you want to have long hair, you can tie a ponytail in the back and cut a diagonal bangs instead of twisting your head. The ponytail is long, the front of the rubber band is slightly fluffy up and down, and the left and right are tight, which will make your face less long. On the contrary, if you stick a little in the back (for example, twist your head), it will look very long in front of you.
It is more convenient for middle school students to tie their heads. If it's short hair, you can try Qi Liuhai. Because there is assistance from both sides.
