trichoscopy alopecia areata androgenetic alopecia vellus hairs peripilar sign

TLDR Asian patients show different trichoscopy features compared to Caucasians, like thicker hair and different alopecia signs.

The document discussed trichoscopy in Asian patients, highlighting some racial differences compared to Caucasian patients. Asian individuals exhibited a greater mean hair diameter and a higher thin hair ratio. In cases of alopecia areata, black dots and regrowing vellus hairs were more easily observed, while yellow dots were less detectable. For androgenetic alopecia, the peripilar sign was less commonly detected, possibly due to the masking effect of normal skin color in Asians compared to Caucasians.
