THE HAIR HAS VARIOUS USES

The special little places from which the hairs grow are very complicated and beautifully made.

Every hair really consists of six layers, all of which are made by the cells of the little hair bulb from which the hair grows.

But each hair requires to be looking after, or it will become brittle and will break off. So there are special glands - usually two to each hair - that produce a kind of oil that keeps the hair soft and pliable, and prevents it from cracking.

Also, every hair has a muscle which is attached to its root, and when this tiny little muscle contracts, it pulls upon the hair and makes it stand upright.

So when we read stories of people whose hair stood on end, it is quite possible that that really might happen, though it is not common.

We scarcely ever use these little muscles, and no one can use them by his own will. Like the hairs themselves, they are relies from the past.
