This study reported that polarized dermoscopy was better for visualizing vascular patterns, scaling, and reticular pigmentation, while nonpolarized mode better documented features like black dots and tapered hair in various hair and scalp conditions.

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 vitamin D levels were lower in alopecia areata patients, with trichoscopic features like broken hairs and black dots more prevalent in cases with vitamin D deficiency.

This study observed that specific trichoscopic features like white peripilar signs, scalp pigmentation, and focal atrichia are associated with advanced female pattern hair loss in Fitzpatrick skin type III patients.

In this study, trichoscopy consistently identified typical findings of frontal fibrosing alopecia, revealing three unusual clinical patterns in 18.4% of patients, which may aid in the differential diagnosis when clinical presentations are atypical.

This study found that trichoscopy using anisotrichosis criteria was 75% sensitive and 61.54% specific in diagnosing early female pattern hair loss in women without visible hair thinning.

The authors concluded that trichoscopy is a valuable noninvasive tool for diagnosing and monitoring nonscarring alopecia, aiding in the identification of new hair signs in difficult cases.

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 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 study found that metabolic syndrome negatively affected the response to intradermal dutasteride injection in female pattern hair loss, with participants showing reduced terminal hair and increased vellus hair compared to those without the syndrome.

This study identified two distinct trichoscopic patterns in the mid-frontal scalp of patients with frontal fibrosing alopecia who also display clinical features of androgenetic alopecia.

This study observed that while both minoxidil and botanically-derived 5-alpha reductase inhibitors significantly increased hair count and diameter in women with female pattern hair loss, minoxidil was more effective, especially for greater hair diameter increases, but had more troublesome side effects.

This study found that trichoscopic parameters in male androgenetic alopecia deteriorated progressively with increasing disease severity and were significantly linked to genetic, metabolic, and psychosocial factors.

This study found that fibrosing alopecia in a pattern distribution in Hispanic male patients often resembles androgenetic alopecia, with a tendency for earlier onset compared to European and North American populations.

This study found that a family history of androgenetic alopecia and specific trichoscopic signs are strong predictors of female pattern hair loss, leading to a nomogram model for risk prediction.

This study examined the clinical patterns and trichoscopic features of female pattern hair loss at a rural tertiary care hospital, but it does not report any specific results.

This study characterizes alopecia in ARCI, highlighting its prevalence among patients with severe forms and revealing new associated trichoscopic features.

In this study, trichoscopy was found to be an effective noninvasive tool for diagnosing female pattern hair loss at early stages, potentially eliminating the need for scalp biopsies.

This study suggests that male androgenetic alopecia and female pattern hair loss follow distinct progression pathways, characterized by different trichoscopic patterns related to hair diameter and follicular unit changes.

In this study, researchers observed that trichoscopy could reliably identify features such as anisotrichosis and signs associated with inflammation and fibrosis in female pattern hair loss, which may aid in assessing disease severity and guiding treatment decisions.

This study suggests that hormonal disturbances play a role in female pattern hair loss and that trichoscopy may be a useful tool for diagnosis and differentiation from other conditions.

In this study, researchers found that trichoscopy helps detect early signs of female-pattern hair loss before it is visible, highlighting its importance for monitoring and managing the condition.

This study found that HLA-B*57 and HLA-Cw*06 were associated with increased risk of psoriasis vulgaris, while KIR2DL2 was more prevalent in controls, suggesting a protective effect.

This study found that trichoscopy can effectively differentiate female pattern hair loss from chronic telogen effluvium based on specific features like hair shaft diameter variability and density differences, aiding in targeted treatment planning.

This report on two Indian male siblings with monilethrix highlights trichoscopy's role in diagnosing this condition, which can be complicated by early-onset androgenetic alopecia.

In this study, researchers found that topical ketoconazole showed delayed hair growth compared to minoxidil in female pattern hair loss but had fewer side effects, though patient satisfaction was similar for both treatments.

This study found that trichoscopic quantitative parameters reliably indicate the severity of female pattern hair loss and complement the Sinclair scale by offering a more objective and reproducible grading system.

This study suggests that traditional classification systems for pattern hair loss, while useful in the past, have limitations in accuracy and reproducibility, and highlights the potential of integrating digital imaging and AI to create more precise and biologically informed classification frameworks.

In this study, trichoscopy was found to enhance the early assessment of minoxidil therapy in males with pattern hair loss, leading to improved satisfaction and treatment compliance by revealing positive changes visible within one month.

The examined study explored how trichoscopic evaluations of female pattern hair loss might relate to disease severity and histological changes, but the authors highlighted methodological issues such as unclear sample size determination and insufficient control of confounding variables, which limit the results' generalizability and reproducibility.
