Multiple Choice

What part of the hair can you see?

The part you can see is the hair shaft. It’s the portion of the hair that extends above the skin’s surface and is made of keratinized, dead cells. The hair root sits below the skin, inside the hair follicle, where the living cells reside and growth occurs. The follicle is the tunnel in the skin that houses the hair and its associated glands, while the sebaceous gland attaches to the follicle and secretes oil to lubricate the hair. So, the visible outside piece is the shaft, not the root, follicle, or sebaceous gland.
