Trichoscopic Findings in Various Alopecias at Tertiary Referral Center: A Cross-Sectional Study

A cross-sectional observational study conducted on 256 patients with alopecia at Vydehi Institute of Medical Sciences and Research Centre in Bangalore, India, found that nonscarring alopecias were more prevalent (93.35%) than scarring alopecias (5.85%). The most common type of nonscarring alopecia was androgenetic alopecia (48.82%), followed by alopecia areata (19.63%) and telogen effluvium (18.75%). Trichoscopy, a noninvasive technique, revealed common follicular features such as yellow dots (61%), short vellus hair (62.8%), and black dots (21.87%). The study concluded that trichoscopy is a valuable tool for diagnosing and monitoring hair disorders, as it can differentiate between nonscarring and scarring hair loss, leading to faster diagnosis and reducing the need for unnecessary biopsies.
