The scale-like outer layer of hair is called the cuticle. It consists of overlapping, flat cells that protect the inner layers of the hair shaft and help to retain moisture. The condition and arrangement of the cuticle can affect the hair's shine, smoothness, and overall health. A healthy cuticle lies flat, while damage can cause it to lift, leading to frizz and breakage.

What is the outer layer of the hair shaft called?
The outer layer of the hair shaft is called the cuticle. It consists of overlapping layers of thin cells that help protect the hair strand and give it its strength and flexibility.
What layer of the epidermal region has scalelike cells full of keratin that constantly flake off?
The outer layer of the epidermis is full of scale like that frequently flake off. These cells are pushed to the surface as they begin to die.
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 are the layer of the hair?
cuticle, cortex, and medulla (outer to inner)
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 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 3 layers of hair?
The three layers of hair are the cuticle (outermost layer), cortex (middle layer responsible for strength and elasticity), and medulla (innermost layer, not always present in all hair types). These layers work together to provide structure and protection to the hair strand.
What is the second layer of hair?
The second layer of hair refers to the cortex, which lies between the outer layer (the cuticle) and the inner layer (the medulla). The cortex is primarily composed of tightly packed keratin fibers and is responsible for the hair's strength, elasticity, and color. This layer contains melanin, which gives hair its pigment, and plays a crucial role in determining the overall texture and appearance of hair.
