The cortex is the part of the hair that plays a crucial role in its strength and overall structure. Located beneath the cuticle, the cortex comprises a dense network of keratin fibers, which provide both tensile strength and resilience to the hair. This is where the bulk of the hair's mass is found, and it contains the majority of pigment, contributing not only to the hair’s color but also to its durability.

Understanding the structure of hair is essential for barbers and cosmetologists, as it helps them make informed decisions about hair treatments and styling options. The cortex's robust nature allows hair to withstand various styling practices that could otherwise damage it, making knowledge about this part critical for maintaining the health and appearance of hair.

The cuticle, while important for protecting the hair fibers and contributing to shine, does not significantly influence the hair's strength. The medulla, primarily found in thicker hairs, has an unclear role in strength, and while it may add some structural integrity, it is not essential for the overall strength of the hair. Finally, the follicle is the living part of the hair located below the skin, responsible for hair growth, but it does not contribute to the hair's strength after it has emerged from the scalp.
