What are the three main layers of the hair shaft?
The three main layers of the hair shaft are the medulla (innermost layer), cortex (middle layer), and cuticle (outer layer). The medulla is the innermost part of the hair shaft, often absent in fine hairs. The cortex provides strength, color, and texture to the hair, while the cuticle is the protective outer layer made up of overlapping scales.
What part of the hair shaft is made of cortical cells?
The cortex layer of the hair shaft is made of cortical cells. It is the middle layer of the hair shaft and provides strength, elasticity, and color to the hair.
What is the Layer of hard keratin that coats the hair?
The layer of hard keratin that coats the hair is called the cuticle. It is the outermost layer of the hair shaft and serves as a protective barrier for the inner layers of the hair.
What is the name of the outside layer of the hair strand?
The outside layer of the hair strand is called the cuticle. It consists of overlapping scales that protect the inner layers of the hair shaft.
What is hair made of?
Hair is made of a protein called keratin, which is also found in nails and the outer layer of skin.

What are cuticle scales?
Cuticle scales are formed from dead cells on the hair cuticle, which is the outer layer of the hair shaft. The scales give the hair shaft strength.

Hair is made of a protein called keratin, which is also found in nails and the outer layer of skin.
What are the three main parts of hair?
Three major parts of hair are Cuticle, Cortex, and Medulla.
What layer is the main part of the hair shaft?
The main part of the hair shaft is located in the cortex layer. This layer is composed of keratin and contains the pigment that gives hair its color. The cortex also determines the strength, elasticity, and texture of the hair.
Where do the cells divide to produce hair?
Hair cells divide in the hair follicle, which is located in the outer layer of the skin called the epidermis. The hair follicle contains stem cells that divide and differentiate to produce new hair cells, eventually forming the hair shaft that grows out of the skin.
What is to fibers as cuticle is to wax?
Hair. A cuticle is the outer layer of hair, just as wax is the outer layer of a fiber at times.
What is visible part of the hair called?
Hair Shaft
Where in the hair are pigment granules found?
Pigment granules, which determine hair color, are found in the cortex layer of the hair shaft. They are produced by cells called melanocytes and are responsible for producing melanin, which gives hair its color.
