A hair develops when a part of this skin goes down into the lower layer and Strikes roots there' Then it shoots upwards through the layers of the skin and comes out as a hair. In the roots of the hair there are four different layers of cells. They divide and multiply and push the shaft of the hair up through the skin. As they move farther away, the hair cells change into a horny material like that of our outer layer of skin.
On the outside surface of the hair, the cells become flattened out and lie on top of one another like shingles. Near the cells of the root there are big, round, fat cells from which come the materials to build the hair. By
the way, the hair root is sort of "screwed" into the tissue. It cannot be torn out. So when you pull out a hair, you do not pull out the root.
Your hair grows at the rate of about 12 millimetres a month. And the surprising thing is, it does not grow at the same speed at-all times. Hair grows very slowly at night, then speeds up in the morning, then slows up till late afternoon, then grows faster again!
