A hair diagram, a visual representation of hair strands and their distribution on the scalp, serves as a valuable tool in various fields. In trichology, it helps identify hair loss patterns and diagnose conditions like alopecia.
Hair diagrams hold significant relevance in hair transplantation. Surgeons use them to plan the extraction and implantation of hair follicles, ensuring natural-looking results. Historically, the development of the Norwood-Hamilton scale in the 1950s provided a standardized method for hair loss classification, facilitating accurate hair diagram creation.
