Nasal hair or nose hair is the hair in the nose. Adult humans have hairs in the anterior nasal passage. Nasal hair has important implications for the health of the human body because a lack of nasal hair could invite the transport of potentially harmful particles into the respiratory system.^{[citation needed]}

Nasal hair should not be confused with cilia of the nasal cavity, which are the microscopic cellular strands that, unlike macroscopic nasal hair, draws mucus up toward the oropharynx via their coordinated, back-and-forth beating.

[edit] Removal

A number of devices have been sold to trim the nose hair, including miniature rotary clippers, and attachments for electric shavers. However, given the putative function of nasal hairs, many physicians recommend trimming them lightly, if at all.^{[citation needed]}

The removal of nasal hair by plucking is extremely painful. The pain is often associated with the unconditioned reaction of tearing eyes and sometimes causes bleeding. These symptoms can be lessened if the plucking occurs in a situation where more warm moisture is present in the nasal passage (e.g. after a shower or steam facial); However, the pain associated with this method of nose hair removal can be a prohibitive factor to its removal for cosmetic purposes. Removal by hand can be less painful, though acquiring a firm grip on a single hair may prove prohibitively difficult for some.^{[citation needed]} A pair of tweezers can be used which facilitates removal and an antiseptic cream applied after treatment on the end of a cotton-bud to reduce the risk of infection and soreness.
