If there are no symptoms of a hair flying in your nose, close observation is recommended. If you feel discomfort in the nose, ask your doctor to take care of it if necessary. A hair flying in the nose may cause irritation to the mucous membrane of the nose, resulting in localized itching, which may cause the symptom of sneezing, through which the hair can be sprayed out. If there are no uncomfortable symptoms, generally do not need special treatment, you can first closely observe. If you feel itchy and uncomfortable inside your nose or have allergic symptoms, we recommend you to go to the ENT department of the hospital for examination, and ask the doctor to take out the hairs with the help of an appliance if necessary. If there are symptoms of allergy, antihistamine drugs such as loratadine and cetirizine should be given if necessary. To summarize, hairs flying in the nose can be closely observed first, and if necessary, go to the hospital and ask the doctor to deal with it.
