Question: 1 / 400

What is the function of the cuticle layer in hair?

To provide color to the hair

To protect the inner structure of the hair

The cuticle layer of the hair serves primarily as a protective shield for the inner structures, which include the cortex and medulla. This outermost layer is made up of overlapping, scale-like cells that fit closely together, much like shingles on a roof. This structural arrangement is crucial as it helps prevent moisture loss and shields the more delicate layers of the hair from physical damage, chemical treatments, and environmental factors.

While other functions associated with hair, such as color, volume, and shine, are influenced by different components of the hair structure and external treatments, the primary role of the cuticle is indeed protection. It is essential for maintaining the integrity and health of the hair by providing a barrier against potential damage.
