Is Trichoscopy a Reliable Method for Differentiation of Frontal Non-Scarring Alopecias?

The study evaluates the reliability of trichoscopy in differentiating frontal non-scarring alopecias, including traction alopecia (TA), male pattern hair loss (MAGA), female pattern hair loss (FAGA), and telogen effluvium (TE), using a sample of 100 patients. It finds that trichoscopic features like hair diameter diversity and single follicular units vary significantly among these conditions, with notable differences in the frontal region for FAGA, MAGA, and TA. The study concludes that comprehensive trichoscopic evaluation across all scalp areas enhances diagnostic accuracy. It identifies specific trichoscopic markers, such as broken hair for TA and lonely hair for MAGA, while acknowledging limitations like the single-center design and small sample size, and calls for further research to standardize findings.
