Correlation of Trichoscopic Findings in Androgenetic Alopecia and the Disease Severity

The study examined the relationship between trichoscopic findings and the severity of androgenetic alopecia (AGA) in 91 patients, consisting of 66 males and 25 females aged 18 to 70 years. It found a positive correlation between clinical and trichoscopic findings regarding disease severity. Hair shaft thickness heterogeneity was the most common feature in both male and female AGA patients. The brown peripilar sign (BPPS) was linked to early grades of AGA, while the white peripilar sign (WPPS) and focal atrichia were associated with later grades. Scalp honeycomb pigmentation was common across all stages but did not correlate with disease severity. The study concluded that trichoscopy is a practical tool for early detection of hair follicle changes and monitoring therapeutic responses in AGA.
