Question: 1 / 400

What is the visible portion of the hair known as?

Hair root

Hair shaft

The visible portion of the hair is known as the hair shaft. It is the part of the hair that extends above the surface of the skin and is composed of dead, keratinized cells. The hair shaft is what we see and style, and it is responsible for the hair's overall appearance, including its length, color, and texture.

Understanding the roles of the other parts helps clarify why they are not correct in this context. The hair root is the portion that is embedded within the follicle beneath the skin, while the hair follicle itself is the structure that surrounds and supports the hair root but is not visible. The hair bulb is located at the base of the hair follicle and houses the living cells that produce the hair, but it, too, is not seen from the surface. Thus, when referring to the part of the hair that is actually visible, the appropriate term is the hair shaft.
