How is hair made?

Answer 1

Hair Comes From Where?Whether hair is growing out of your head, arm, or ankle, it all rises out of the skin in the same way. It starts at the hair root, a place beneath the skin where cells band together to form keratin (the protein that hair is made of). The root is inside a follicle(say: fol-ih-kul), which is like a small tube in the skin.

As the hair begins to grow, it pushes up from the root and out of the follicle, through the skin where it can be seen. Tiny blood vessels at the base of every follicle feed the hair root to keep it growing. But once the hair is at the skin's surface, the cells within the strand of hair aren't alive anymore. The hair you see on every part of your body contains dead cells. That's why it doesn't cause pain when someone cuts your hair with scissors!

Nearly every hair follicle is attached to a sebaceous(say: sih-bay-shus) gland, which is sometimes called an oil gland. These sebaceous glands produce oil, which makes the hair shiny and a bit waterproof. Sometimes, like during puberty, these glands can pump out too much oil and a person's hair may look greasy. Time for a shampoo!

Answer 2

Hair grows from follicles within the skin. The part of the hair inside the follicle (below the skin's surface) is known as the hair root, while the portion you see protruding from the head is the hair shaft. At the base of the hair root is the hair bulb where nutrients are received and new cells are formed.
