TrichoScan androgenetic alopecia trichoscopic images hair density ImageJ software AGA hair loss hair count

TLDR TrichoScan needs optimization as it underestimated hair density by 38.9% compared to manual counting.

This study aimed to evaluate the utility of TrichoScan analysis by comparing it with manual hair counting on trichoscopic images in male patients with androgenetic alopecia. Ninety TrichoScan analyses were enrolled, and hair counting was performed by two independent dermatologists' blind evaluation by manual marking of all hairs using freely available image analysis tool, the ImageJ software. The concordance between manual counting of hairs on trichoscopic images and TrichoScan analysis was unsatisfactory. Hair density was underestimated by 38.9%, and several hair fibres were undetected by TrichoScan. The study concluded that optimization is still required for TrichoScan analysis.
