ROOT OF A HAIR Meaning and
Definition
-
The root of a hair refers to the base or lowermost part of an individual hair strand that is deeply anchored within the skin. It is the section of the hair that is situated beneath the surface of the scalp or any other area of the body where hair grows. The root consists of several important components that contribute to hair growth and maintenance.
One vital component found within the root is the hair follicle, which surrounds and protects the root. The hair follicle is responsible for producing new hair cells, which push older cells upwards, creating the hair strand. Additionally, blood vessels connected to the root supply vital nutrients and oxygen required for hair growth.
The root of a hair also includes the papilla, a small, nipple-like projection at the base of the follicle. The papilla contains specialized cells that enable hair growth and maintenance. It receives these essential nutrients and oxygen from the blood vessels and delivers them to the surrounding cells. The matrix, a region within the root and just above the papilla, is where active cell division takes place, resulting in the formation of new hair cells.
Overall, the root of a hair plays a crucial role in the growth, development, and maintenance of hair. By housing the follicle, papilla, and matrix, it ensures that the hair receives the necessary nourishment and support to thrive and sustain its function.
