The ones far back in your nose are sweepers. These keep your nose from running all the time, by sweeping the mucus back into your throat. The hairs just inside your nostrils are like guards. They keep things like dust and bugs from getting in.

It’s a good thing they’re always on duty.

When you brush your hair, have you ever noticed that some comes out? This is completely normal. The tiny pits, or follicles (foll-i-cles) the hair grows from has just become tired. Because hair is constantly growing, the follicles have to work very hard to push the hair out.

In older people, however, sometimes the follicles are just so tired they stop working altogether. Kind of like retirement. These people will have thin hair or patches without any hair at all. For some people, all their follicles retire and they go completely bald. 

Most babies have very little hair on their heads when they’re born. But before they were born, they were covered in hair. They even had a beard!  

A very fine, silky hair called lanugo, (luh-noo-goh) first starts growing on the baby’s face while it’s inside the mother. This hair then grows all over the baby until about a month before it’s born. Then most of it falls out. I guess we all had baby beards at one time.
 
What if you had so much hair you could actually use it as a jump rope?  

A woman in China can. Her hair is 5.627 meters or 18 feet 5.54 inches long. It’s considered the longest hair in the whole world!
