Four Fixed Points for Dermoscope in Male Androgenetic Alopecia: A Way to Diagnose and Monitor Therapy Effect

The paper presents a method to diagnose and assess the severity of androgenetic alopecia (AGA) in men, as well as evaluate the effectiveness of treatment using a dermoscope. The method involves capturing images at four specific points on the scalp: the temporal angle, baihui acupoint, hair whorl, and occipital tuberosity. These points represent different regions of hair loss in male AGA, with the occipital tuberosity serving as a marker of a region with no hair loss. By comparing dermoscopy images of these four regions, doctors can diagnose AGA, assess its severity, and evaluate the effectiveness of treatment. This provides a visual way to assess treatment efficacy, which can help doctors decide if a change in treatment is necessary and give patients confidence to continue their treatment.
