Question: 1 / 400

What are the three primary parts of hair?

Cuticle, cortex, medulla

The three primary parts of hair are the cuticle, cortex, and medulla. The cuticle is the outermost layer of the hair strand, composed of overlapping cells that help protect the inner layers and maintain moisture. The cortex lies beneath the cuticle and is the thickest layer, containing the fibrous proteins that give hair its strength and elastic properties. It is also responsible for the pigmentation of hair. The medulla is the innermost layer, which may be absent in fine hair types but can contribute to the overall structure and shape of the hair.

Understanding these three components is essential for barbers as they impact hair health, appearance, and how hair reacts to various treatments and styling techniques. Knowledge of the structure of hair helps in choosing the right products and methods for cutting or coloring hair, ultimately contributing to better client results.
