TLDR Human hair is complex and grows in cycles starting from embryonic life.
The document detailed the ultrastructure, function, and formation of hair, focusing on the cuticle, cortical, and medullary cells. Cuticle cells overlapped in a specific pattern, contributing to the surface properties of mammalian fibers. Cortical cells were categorized into orthocortical, paracortical, and mesocortical types based on staining characteristics. The medulla, present in coarser hairs, contained vacuoles and medullary granules. Intercellular connections between various cell types were crucial for the mechanical and chemical properties of fibers. The study highlighted the importance of these cellular structures in applications ranging from textiles to biodegradation.
