Nasal hair

Nasal hair or nose hair is the hair in the nose. Adult humans have hairs in the anterior nasal passage. Nasal hair functions 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 pharynx via their coordinated, back-and-forth beating.
==Removal==
A number of devices have been sold to trim nasal hair, including miniature rotary clippers and attachments for electric shavers. 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 swab to reduce the risk of infection and soreness.
