TLDR The paper suggests a way to diagnose male hair loss and check treatment results using a dermoscope at four specific scalp points.

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.

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
