What term refers to the section of the hair that is attached to the scalp?

The correct term for the section of the hair that is attached to the scalp is the root. The root is the part of the hair that resides beneath the surface of the skin, specifically in the hair follicle, and is essential for hair growth and nourishment. It comprises the living cells that divide and grow, which ultimately produce the visible part of the hair shaft that extends above the scalp.

The root is crucial because it contains the hair bulb, where the hair growth originates, and is surrounded by a network of blood vessels and nerves that contribute to the overall health of the hair. Understanding the role of the root can help in recognizing issues related to hair growth and scalp health.

While options like strand, base, and tip refer to different aspects of hair and its structure, they do not accurately describe the section of hair that attaches to the scalp. A strand typically refers to a single piece of hair, the base could refer to the initial area from which the hair grows but is not the term used for the section adhering to the scalp, and the tip denotes the end of the hair shaft, which is farthest from the scalp.
