Nasal hair or Nose hair consists of the usually small hairs that are in the nose, especially those near the nostrils. Biologically, the hairs act as a filter and keep dust and dirt out of the nasal passages, and strongly stimulate pain nerves if pulled out. They also help to maintain humidity in the air passages by trapping humidity as one exhales, while evaporation of trapped moisture on the hairs humidifies inhaled air.

Loss of nasal hair due to alopecia areata (a form of hair loss that causes bald spots) has been linked to increased severity of asthma, seasonal allergy and atopic dermatitis (skin irritation caused by hereditary hyper-sensitivity).

In some cultures nose hair protruding from the nostrils may be thought unattractive. A number of devices have been sold to trim the nose hair, including miniature rotary clippers and attachments for electric shavers.
