trichoscopy androgenetic alopecia hair shaft thickness heterogeneity white peripilar signs focal atrichia AGA

Studysummary This study found that trichoscopic examination in patients with androgenetic alopecia revealed that hair shaft heterogeneity was common, while the white peripilar sign and focal atrichia were associated with more advanced disease stages in both genders.

The study on 63 patients (51 males and 12 females) in India found that trichoscopy is a valuable tool for diagnosing androgenetic alopecia (AGA) and assessing its severity. Hair shaft thickness heterogeneity (HSTH) was identified in all patients, marking it as a key indicator of AGA. More severe stages of AGA were linked to white peripilar signs and focal atrichia, which may indicate a need for surgical intervention. The study underscores trichoscopy's role in diagnosis, treatment planning, and patient counseling, though it notes the limitation of not having follow-up data to evaluate changes after treatment.
