This study reviewed 39 studies with 3204 patients to identify characteristic trichoscopic findings in alopecia areata, highlighting yellow and black dots, broken, short vellus, and tapering hairs as key indicators. It found no single diagnostic trichoscopic finding but observed trichoscopy's utility in monitoring treatment response.

This study found that RCM combined with dermoscopy can differentiate disease states between alopecia areata, tinea capitis, nevus sebaceous, and linear scleroderma of the scalp by identifying distinct dermal and follicular patterns.

In this study, the authors compared trichoscopy findings for different forms of diffuse non-cicatricial alopecia in females and suggested that trichoscopy might often replace the need for histopathological confirmation, reserving biopsies for more uncertain cases.

This report describes a rare case of alopecia areata coexisting with primary scarring alopecia, diagnosed through detailed trichoscopic investigation, highlighting the importance of comprehensive examination for accurate diagnosis.

This review summarizes the main trichoscopic findings for diagnosing common hair and scalp disorders, but reports no new clinical results.

This review examines the use of dermoscopy for diagnosing common hair disorders and highlights its importance, but it does not report new clinical results.

This study identified key dermoscopic markers such as yellow dots, black dots, broken hairs, and coudability hairs, which were associated with a poorer prognosis in alopecia areata patients.

This study found trichoscopy to be a highly sensitive, non-invasive method for diagnosing tinea capitis in children, which could be valuable in resource-limited settings lacking mycological culture facilities.

This article reviews the use of dermoscopy as a noninvasive tool for diagnosing various types of nonscarring alopecia but presents no new clinical findings.

Using Excimer light with topical steroids is the most effective treatment for alopecia areata.

This case report describes a 50-year-old man with folliculotropic mycosis fungoides stage IB, noting trichoscopic findings like dilated follicular openings, black dots, and dystrophic hairs, which are less commonly documented in this condition, suggesting trichoscopy could aid in early diagnosis.

This study found that in patients with alopecia areata, trichoscopy was a valuable tool for monitoring disease activity, severity, and therapeutic response, showing changes in trichoscopic markers that preceded improvements observed in the hair pull test.

This study found that yellow dots, black dots, exclamation mark hairs, broken hairs, and nail changes observed through dermoscopy are related to the severe form of alopecia areata.

This article discusses the diagnostic methods for differentiating alopecia areata from similar hair loss conditions and emphasizes the importance of accurate diagnosis, but it reports no new research findings.

This study found that short vellus hair and yellow dots are common dermoscopic findings in alopecia areata, with variations indicating disease activity or remission.

This study found that yellow dots were the most common trichoscopic finding in adult patients with alopecia areata, observed in 88.5% of cases.

Trichoscopy helps tell different hair loss types apart using specific scalp and hair patterns.

A girl with red hair developed hair-pulling and body image disorders after being bullied for her hair color.

This study reviews the diverse clinical presentations of tinea capitis, such as gray patches, a "black dot" appearance, and kerion, highlighting its complex differential diagnosis with conditions like alopecia areata and psoriasis.

This study found trichoscopy to be a reliable non-invasive method for diagnosing various forms of alopecia, aiding in clinical management and reducing the need for biopsies in a hospital-based setting with 90 patients, including those with uncertain diagnoses.

This study found trichoscopy to be a quick and effective method for diagnosing and monitoring tinea capitis in children, with improvements in trichoscopic features observed by week 2 and full recoveries confirmed mycologically by week 8.

The researchers observed that in cases of alopecia areata with atypical features, histopathological confirmation may be necessary, as trichoscopic clues like loss of follicle ostia and vellus hairs were common, while typical features such as exclamation mark hairs were not always present.

In this study, researchers reported that dermatoscopy effectively differentiates between various types of alopecia and scalp disorders, offering a fast, minimally invasive diagnostic method that improves the standard of care and reduces the necessity for scalp biopsies.

In this study, patients with Alopecia Areata showed significant clinical improvement after intralesional steroid treatment, as trichoscopic features like black dots and exclamation mark hairs decreased, while short vellus and circle hairs increased, highlighting Trichoscopy's utility in monitoring treatment response.

This study found that line-field confocal optical coherence tomography effectively visualized microscopic alterations in alopecia areata, suggesting its potential use in diagnosis and monitoring.

This study observed a high prevalence of severe markers among pediatric alopecia areata patients, identifying AA subtotalis as more frequent, with nail changes and various hair markers suggesting progression to severe forms.

This review discusses various non-invasive methods for diagnosing alopecia areata, highlighting that trichoscopy signs like short vellus hairs and yellow dots are sensitive indicators of the condition, while advanced imaging techniques provide valuable information on hair follicle status and scalp inflammation.

This study found that trichoscopy is a valuable tool for diagnosing various hair disorders by identifying specific trichoscopic patterns, such as hair diameter diversity in androgenetic alopecia and exclamatory marks in alopecia areata.

This study found no significant associations between dermoscopic findings and the severity or stage of alopecia areata in children, though there was a notable correlation with nail findings.

This study aims to describe the trichoscopic pattern of chemotherapy-induced alopecia and its changes during different phases of chemotherapy.
