Question: 1 / 400

What is the function of the cuticle in hair?

Dissolving oils in the hair

Providing shine to the hair

Protecting the inner layers of hair

The cuticle serves a crucial role in the structure of hair by acting as a protective barrier for the inner layers. It is the outermost layer of the hair shaft and is composed of overlapping, transparent cells that resemble roof shingles. This protective layer helps prevent damage from environmental factors, such as heat, chemicals, and pollutants, which can affect the underlying cortex and medulla.

By shielding these inner layers, the cuticle contributes to maintaining the hair's overall health and integrity. A well-preserved cuticle can also help retain moisture and prevent excessive drying or brittleness, allowing the hair to remain strong and resilient. This protective function is essential for preventing breakage and damage, thereby supporting the overall quality and appearance of the hair.
