This is called a nose clip. Nose hair clip is a special clip for repairing nose hair, which is used more by men and less by women. Nose hair belongs to the short hair of the human body. Like eyebrows, the human body has short hair and long hair. For example, hair is long, and short hair will become longer with age, which is also a common physiological phenomenon. The older you get, the longer your eyebrows and the longer your nose hair. There is no special way to cut it, or use a nose hair clip to pull it out and trim it once every two or three days. Don't destroy the hair follicles inside the nose hair, which is harmful to health.
