What is the significance of the cuticle layer in hair?

It adds color to hair
It protects the inner layers of the hair shaft
It helps hair retain moisture
It determines hair thickness

The correct answer is: It protects the inner layers of the hair shaft

The cuticle layer in hair plays a crucial role in protecting the inner layers of the hair shaft. This outermost layer consists of overlapping scale-like cells that form a barrier, shielding the more delicate cortex and medulla beneath from environmental damage, such as UV rays, heat, and chemical exposure. Its protective function is vital to maintaining the integrity of the hair structure, preventing damage, and ensuring that the hair remains healthy and strong. The other options do not accurately describe the role of the cuticle. The cuticle does not add color to hair, as that is primarily determined by pigment located in the cortex. While the cuticle can influence moisture retention to some extent, this is more significantly influenced by the condition of the cortex and the presence of hair oils and conditioning agents. Additionally, hair thickness is largely determined by the size and number of hair follicles and is not something the cuticle layer is responsible for.
