Trichoscopic Patterns of Nonscarring Alopecia’s

Abstract

Background: Hair loss (alopecia) is a common problem and is a major cause of psychological stress and anxiety among affected individuals. It is of utmost importance to diagnose these cases at the earliest and treat them accordingly. Trichoscopy provides a noninvasive option that can be used for early diagnosis and monitoring the progression of the hair disorders. Aims and Objectives: To perform trichoscopy and document the findings in patients with nonscarring alopecia’s. Materials and Methods: A total of 100 cases satisfying the inclusion criteria were screened for general physical examination and scalp examination including hair shaft and root, and tests for hair anchorage and fragility were also done. The lesions were examined through dermoscope, photographs were taken, and findings were documented. Results: Among the total of 100 cases screened, 57 were female and 43 were male. The mean age of the study group was 26 ± 14.8 years. Females were affected by alopecia areata (AA) and female pattern hair loss (29.8%) equally, whereas males were most commonly affected by AA (41.8%). The common trichoscopic follicular features noted were broken hair (48%), black dots (48%), single hair follicle unit (45%), short vellus hair (44%), upright hair (41%), and yellow dots (40%). The common interfollicular features seen were honeycomb pigmentation (26%) and arborizing red lines (12%). Conclusion: The emergence of newer hair signs on trichoscopic studies aids in identification and has a definitive role in the diagnosis of clinically difficult cases, so it is recommended to use trichoscopy in the routine examination of nonscarring alopecia’s.
