Question: 1 / 400

What is the role of the cuticle in a hair strand?

To enhance color absorption

To protect the inner layers of the hair and provide shine

The cuticle is the outermost layer of the hair strand and serves a crucial protective function. It consists of overlapping, scale-like cells that lie flat and work together to shield the inner layers of the hair, which include the cortex and the medulla. This protective barrier helps prevent damage from environmental factors such as UV rays, heat, and chemicals.

In addition to its protective capabilities, the cuticle also contributes to the overall appearance of the hair by providing shine. When the cuticle lies flat and is in good condition, it allows light to reflect off the hair more effectively, giving it a shiny and healthy look.

Understanding the role of the cuticle is essential in the field of cosmetology, as it can influence how hair responds to various treatments, including coloring and conditioning. Maintaining the integrity of the cuticle is vital for overall hair health and aesthetics.
