Question: 1 / 400

What is the function of the cuticle layer of hair?

To provide moisture

To protect the inner layers of the hair

The cuticle layer of hair serves as a protective outer covering for the inner structures of the hair shaft, which include the cortex and medulla. Comprising thin, overlapping, scale-like cells, the cuticle helps shield the inner layers from environmental damage, chemical treatments, and physical stressors. This protective role is crucial for maintaining the integrity and health of the hair, as it reduces the likelihood of breakage and damage that can occur from exposure to heat, pollutants, and harsh styling products. Therefore, the fact that the cuticle acts as a barrier to safeguard the more delicate and essential components of the hair makes the selected answer accurate in identifying its primary function.
