    width of an individual hair strand, measured in micrometers

    Hair Diameter, also known as hair shaft diameter or hair thickness, refers to the width of an individual strand of hair. It is typically measured in micrometers (µm) and can vary significantly among individuals and even among different hairs on the same person. This measurement is important for understanding hair texture, strength, and overall health, and it can influence how hair responds to styling and treatment products.
