This study identified several specific trichoscopic features of trichotillomania, with trichoptilosis, V hair, and hair powder being the most frequent findings.

In this study, researchers found that a low-cost USB dermoscope can effectively detect microscopic hair changes associated with early female pattern hair loss, making it a useful tool for diagnosis even without expensive equipment or programs.

This study found a strong correlation between the Sinclair Scale and cumulative hair thickness density, allowing the estimation of the Sinclair Scale from trichoscopy-derived statistics.

This article discusses the presence of dirty dots as a normal trichoscopic finding in children, noting they are not observed in adults or other age groups, and reports no new results.

This article discusses the diagnostic challenges of evaluating hair and scalp conditions in patients using hair dye, emphasizing how dyes can mimic different pathologies and lead to contact dermatitis.

This review covers trichoscopy's role in diagnosing scalp disorders, emphasizing its potential to improve clinical accuracy, but it reports no new clinical results.

This study introduced a non-invasive, three-step diagnostic algorithm for alopecia that combines clinical and trichoscopic features to accurately identify alopecia subtypes, potentially reducing reliance on invasive histopathology.

This review discusses the use of trichoscopy for diagnosing systemic diseases and concludes that certain trichoscopic features may help dermatologists suspect these conditions.

This study observed that videodermoscopic assessments of dermatomyositis patients revealed specific vascular and pigmentary features, suggesting it may be useful for preliminary diagnosis.

This study highlights the importance of recognizing artifacts in trichoscopy, as certain cosmetic products can mimic signs of early androgenetic alopecia.

This article reviews trichoscopic techniques for diagnosing common hair loss conditions and presents a revised algorithm for identifying specific features of cicatricial and noncicatricial alopecia, but reports no new clinical results.

In this study, trichoscopy was used to diagnose female androgenic alopecia with 92% specificity by identifying specific hair and scalp patterns.

This review examines the trichoscopic characteristics of scalp DLE and LPP, correlating these findings with histopathological data, but provides no new clinical results.

Clinical signs don't match inflammation levels in lichen planopilaris and frontal fibrosing alopecia.

The authors concluded that trichoscopic examination can be useful for diagnosing syphilitic alopecia in patients with idiopathic alopecia, though the findings are nonspecific and further studies are needed.

This study found that high-frequency ultrasonography may effectively distinguish different stages of alopecia areata and differentiate it from other scalp conditions.

This study determined that trichoscopy is a sensitive and specific tool that effectively aids in diagnosing alopecia in women, especially when clinical diagnosis is uncertain.

This study found that androgenetic alopecia was the most common cause of frontal hairline recession in Egyptian female patients, supporting the use of trichoscopy as a noninvasive diagnostic tool.

This study found that Follicular Maps, derived from trichoscopic images, remained consistent over time and unaffected by hair cycling or noncicatricial alopecia, offering a precise tool for diagnosing and monitoring hair and scalp conditions.

This report highlights that trichoscopy is a useful, non-invasive tool for diagnosing tinea capitis in children, particularly in areas where lab facilities are limited.

This case report found that dermoscopy, showing characteristic "comma" and "corkscrew" hairs, effectively identified tinea capitis in a 7-year-old girl, allowing for early treatment before confirmation with fungal culture.

This study observed that trichoscopy of long-lasting lesions in a chronic stage revealed specific features such as absence of follicular openings, cicatricial patches, and thick arborizing vessels.

This review discusses the characteristic trichoscopy patterns useful in differentiating lichen planopilaris and frontal fibrosing alopecia from similar conditions but reports no new clinical results.

In this study, trichoscopic examination revealed that patients with androgenetic alopecia had significantly more yellow dots, pilosebaceous units with one hair, and increased perifollicular hyperpigmentation compared to healthy controls.

This case report describes how trichoscopy helped diagnose tinea capitis disguised as female pattern hair loss in cases of endothrix infection, highlighting its usefulness in avoiding misdiagnosis.

This abstract reviews the bubble hair abnormality caused by high-temperature styling tools and reports no new experimental results.

This review describes distinct trichoscopic findings for various alopecias in individuals with skin of color, but reports no new clinical results.

In this study, researchers found that adults with alopecia areata exhibited trichoscopic features of empty follicular openings and tulip hair, while children showed more honeycomb pigment patterns and pohlpinkus constriction on their scalp lesions.

This study identifies specific trichoscopic features such as empty follicles and perifollicular erythema in Caucasians with frontal fibrosing alopecia, which may assist in diagnosis and monitoring, but stresses the need for further research due to limited demographic data.

This systematic review evaluated 60 studies on trichoscopy in hair and scalp disorders, revealing gaps in accounting for variables like disease stage or hair texture, and underscoring a need for more comprehensive analyses to fully understand trichoscopic patterns.
