Why does nose hair grow long when you get older?

Updated November 21, 2016

Nasal hair is normal, and it helps you to stop allergens and particles in the air from being inhaled. Nose hair that is growing long enough to protrude out of your nose may not be attractive, but it is also normal. As we become older, nose hairs tend to get a little longer.


There are varied influences, hormones, medication and genetics that control hair growth in different places on the body, according to Dermatology Online's Slobodan M. Jankovic and Snezana V. Jankovic. For example scalp and pubic hair are influenced by sex-related hormones while other hair, like the nose, may not be.


As we age, our hair changes. Hair on the scalp may begin to lose colour and turn grey in your 30s. Body hair, including nose hair, turns grey later or may not change at all.


Androgens cause axillary (armpit), scalp, legs and arm hair to grow less as we age, however nose hair does not seem to be effected because it grows more with age.


As you age you may grow longer nose, ear and eyebrow hairs. Dr. Edward Schneider, University of Southern California, says this hair growth is partially genetic, but the other causes are not known. Hormone changes may play a role. Nose hair growth is more common in men, however women may grow facial hair on the chin and upper lip instead.


There are many types of trimmers, such as special scissors, electric trimmers and tweezers, that can be used to cut back growing nose hair. Bacterial infection in the nose can be dangerous, so make sure to clean devices before use and clean the nasal area.
