How The Body Works

  How The Body Works?

Hair:

The hair can grow almost anywhere in the body, some can be seen but most can't. This is because hair is important, every strand of your hair has a purpose. The hair in your head keeps your head warm, as for eyebrows and eyelashes it protects your eyes from getting any dust, dirt and even your sweat from your eyes, and almost the rest of the hair in your body keeps you warm.  

How does hair grow?
It all begins underneath the surface of your skin where two hair follicle merge, eventually a hair bulb will appear and that's where cells multiply and the begins to grow out of the follicle, once the hair is outside the skin's surface the cells die therefore it won't hurt to cut it with scissors.

Why do hair look shiny?
The reason behind why most hair is shiny is because of a liquid called a sebaceous glance. Sometimes sebaceous glance produce to much oil so a person's hair looks greasy.

Why do hair come in different colours?
It depends on how much melanin a strand of hair contains. The less melanin the lighter it gets, a person that has blonde hair has less melanin that a person that has black hair. We lose our melanin as we get older.
