Introduction:
Differentiating types of hair loss in the female population is often challenging because these conditions frequently present with overlapping clinical features, especially in early or diffuse forms of hair loss. Quantitative digital trichoscopy allows objective assessment of hair and follicular parameters and may improve diagnostic accuracy. The objective of this study was to compare regional quantitative digital trichoscopic features in female patients with androgenetic alopecia (AGA) and chronic telogen effluvium (TE) under comparable clinical conditions, and to identify parameters useful for differentiating miniaturizing from non-miniaturizing alopecia.
Methods:
This cross-sectional single-center study included 143 adult female patients with chronic TE (n = 74) and AGA (n = 69). Standardized digital trichoscopy was used to assess quantitative parameters in three scalp regions, followed by regional and intergroup comparisons and correlation analyses.
Results:
Chronic TE demonstrated preserved trichoscopic parameters across scalp regions, whereas AGA showed region-dependent miniaturization-related changes, with the strongest discriminatory pattern observed in the frontal scalp.
Conclusions:
Regional quantitative digital trichoscopy allows differentiation between common causes of female hair loss, particularly through frontal scalp assessment.
