Hair growth, the process by which hair strands develop and lengthen, is an ongoing cycle on the human scalp. Environmental factors, nutrition, genetics, and hormones influence the rate and quality of this process.
Hair growth is essential for maintaining a healthy appearance and self-confidence. It provides protection from sun exposure, insulates the head, and enhances sensory perception. Historically, hair growth has been associated with cultural and religious significance, with various styles and lengths holding symbolic meaning in different societies.
