A healthy, compact cuticle layer is responsible for which property of the hair?

1. Color

2. Density

3. Shine and silkiness

4. Strength

The correct answer is: Shine and silkiness

The healthy, compact cuticle layer of the hair is primarily responsible for the shine and silkiness of the hair. The cuticle consists of overlapping, flat cells that form a protective barrier over the inner layers of the hair. When the cuticle is in good condition, it lies flat and smooth, allowing light to reflect off the surface of the hair more effectively. This reflection contributes to the shine, making the hair appear glossy and healthy. Additionally, a well-maintained cuticle also helps to minimize frizz and enhance the overall texture, which contributes to the silkiness. Damage to the cuticle, such as through chemical treatments or environmental factors, can lead to a rough, uneven surface, resulting in a dull appearance and a lack of smoothness. The other properties mentioned, such as color, density, and strength, are influenced by factors like the hair's medulla and cortex, the distribution of pigment in the hair, and the amount of hair follicles, rather than the condition of the cuticle. Thus, the cuticle plays a critical role specifically in the shine and silkiness of the hair.
