Which layer is the center of the hair?

Cortex
Cuticle
Medulla
Scalp

The correct answer is: Cortex

The center of the hair is known as the medulla. This innermost layer is most commonly present in thicker hair types and plays a role in the overall structure and properties of the hair strand. The medulla is often described as a soft, spongy layer made up of air-filled cells. The cortex is the middle layer of the hair shaft where most of the hair's strength, color, and texture are derived. While it is crucial for defining the characteristics of hair, it is not the center. The cuticle is the outermost protective layer that encompasses the hair shaft. It contributes to the shine and smoothness of hair but does not serve as the center. The scalp, while an important part of hair health and growth, is not a layer of the hair itself. Understanding the roles of each part of the hair structure allows for better hair care, styling, and treatment choices in cosmetology.
