Cortical Hair Shaft Cells

Cortical Hair Shaft Cells are specialized cells that constitute the bulk of the hair shaft, forming the central core of each individual hair strand. These cells are part of the hair follicle, an anatomical structure in the skin responsible for hair growth. The cortical cells are surrounded by cuticle cells, which provide a protective outer layer to the hair shaft. The cortex contains keratin proteins and melanin, contributing to the strength, elasticity, and pigmentation of the hair. The arrangement and structure of cortical cells influence the texture and characteristics of the hair, such as straightness or curliness. Cortical hair shaft cells undergo a differentiation process within the hair follicle, transforming into keratinized cells that constitute the bulk of the hair shaft. As new cells form at the base of the follicle, older cells are pushed upward, eventually becoming part of the visible hair strand. The health and integrity of the cortical cells are influenced by factors such as nutrition, genetics, and overall hair care practices. Understanding the biology of cortical hair shaft cells is essential for addressing various hair-related conditions, including hair loss and changes in texture. Research in this field contributes to the development of products and treatments aimed at promoting hair health, resilience, and appearance. In summary, cortical hair shaft cells are central to the structure and characteristics of the hair shaft, playing a key role in determining the unique properties of individual hair strands.
