Human hair thickness, a critical aspect of hair science, refers to the diameter of individual hair strands. It varies widely, influencing hair's texture, volume, and overall appearance.
Understanding human hair thickness is essential for hair care professionals and individuals seeking optimal hair health. Its relevance extends to fields such as forensic science and anthropology, where hair samples provide valuable insights. Historically, hair thickness was often measured using subjective methods, but advancements in microscopy and technology have led to more precise measurements.
