Aren't people born with nose hair? It's for catching snot and er, filtering stuff. I swear I have had it ever since I can remember, you can always just see it (dark hair), and if I flare my nostrils it tufts out a bit.
I am fairly well-groomed (I pluck lots of things ) and it has never occurred to me to remove it.
Are we talking something more extreme than normal nose hair.
I have too much nostril hair (traps bogies - TMI sorry) and have resorted to using one of these. It works brilliantly although it does make me feel like an old man to have one . Do not even think of tweezing your nostril hairs unless you enjoy pain!!
