The structure of hair, which includes the cuticle, cortex, and medulla, is essential to understanding how to care for it properly. Each of these layers plays a distinct role in the hair's overall health and appearance.

The cuticle is the outermost layer, consisting of overlapping, scale-like cells that protect the inner layers. Its health affects the shine and smoothness of the hair; if the cuticle is damaged, the hair can look dull and feel rough. Treatments such as conditioning or oiling aim to repair or smooth the cuticle.

The cortex makes up the bulk of the hair and contains keratin and melanin, contributing to the hair's strength and color. Damage or changes in the cortex can impact texture and elasticity, which is crucial when selecting styling or coloring products. Understanding this layer helps professionals choose the right treatments to maintain strength and minimize breakage.

The medulla is the innermost layer and may not be present in all hair types. While it’s less critical for hair care decisions, it contributes to the overall structure of the hair.

By comprehending how these layers function, cosmetologists can better determine the most effective products or treatments for their clients, leading to healthier hair and more satisfying results.
