Alopecia Classifications Facilitated Accurate Diagnosis, Targeted Therapy, and Precise Prognosis

Alopecia classifications facilitated accurate diagnosis, targeted therapy, and precise prognosis. The most common types included androgenetic alopecia, telogen effluvium, alopecia areata, and cicatricial alopecia. Cicatricial alopecia was characterized by the loss of follicular ostia, while androgenetic alopecia caused early hair loss in both males and females. Hair loss could occur through various mechanisms, including defective or traumatized hair shafts. A multifactorial classification was developed to study parameters like facial distances, scalp laxity and thickness, and hair coverage, aiding in the diagnosis of cicatricial alopecia.
