Hair is a keratinous filament growing from the epidermis of mammals, primarily functioning as protection, insulation, and sensory input. Each hair strand grows from a follicle deep within the skin and consists of two main parts: the root, which is embedded in the follicle, and the shaft, which is the visible part above the skin. Human hair varies in texture, color, and density, all of which are influenced by genetic factors. While head hair provides thermal insulation and protection from UV radiation, body hair plays roles in sensory detection and in the enhancement of sweat evaporation for cooling. Hair growth occurs in cycles, including growth, cessation, and rest phases, which determine the length and overall health of the hair. In addition to its biological functions, hair has significant cultural and aesthetic importance, influencing concepts of beauty and personal identity across different societies.
