TLDR Hair color is influenced by genetics and can indicate certain health conditions.
Hair pigmentation significantly affects visual appearance and social interactions, with melanin producing various hair colors. Follicular melanogenesis relies on genetic, biochemical, and physical factors, as well as epithelial-melanocytic interactions. Genetic changes, pigment transfer defects, and impaired signaling pathways can lead to clinical conditions. The document updates recent scientific advances in follicular melanogenesis and its pathological changes related to specific diseases.
