Nasal hair or nose hair is the hair in the nose. Adult humans have hairs in the anterior nasal passage. Possible functions for nasal hair include filtering foreign particles from entering the nasal cavity and collecting moisture. In support of the first function, the results of a 2010 study indicated that increased nasal hair density decreases development of asthma in those suffering from seasonal rhinitis, possibly due to an increased capacity of the hairs to filter out pollen and other allergens.
Nasal hair should not be confused with cilia of the nasal cavity, which are the microscopic cellular strands that, unlike macroscopic nasal hair, draw mucus up toward the oropharynx via their coordinated, back-and-forth beating.
A number of devices have been sold to trim nasal hair, including miniature rotary clippers, and attachments for electric shavers, as well as spring-loaded nose hair pluckers. The trimmers shorten the hair to such lengths so that they do not appear outside of the nasal passage. A pair of tweezers have been historically used to facilitate the removal of such hairs. Other means are in effect such as waxing and painless extractions with said devices, while it is also noted to apply an antiseptic cream after treatment on the end of a cotton-bud to reduce the risk of infection and soreness. It should also be noted that the removal of several hairs at a time is not a cause for alarm, nor does it ever lead to follicle bleeding, as proven for decades by salons world-wide, which consistently provide hair waxing treatments.
