Comment on a Cross-Sectional Observational Study to Correlate the Trichoscopic Findings of Female Pattern Hair Loss with the Disease Severity and Underlying Histopathological Changes

The letter to the editor critiques a study on female pattern hair loss (FPHL) that aimed to correlate trichoscopic findings with disease severity and histopathological changes. The study involved 90 participants but lacked justification for the sample size and details on participant recruitment, raising concerns about selection bias. The methodology section was not self-explanatory, missing details on confounding factors, device standardization, and biopsy procedures, which affects reproducibility and validity. The discussion section was inadequate, failing to explore reasons for the results. Despite these issues, the study highlights the importance of trichoscopic evaluation in patients with hair loss.
