Comb your hair with a jade comb.

Don't comb it to the end. Because picking up the jade comb from the hair root and combing it from top to bottom will not only easily lead to knotting of hair, but also tear off some "innocent" hair. The correct way to comb your hair is to hold a hair first, comb the messy ends, then comb it from the middle to the ends, and finally comb it slowly from the root to the ends.
