In this hospital-based cross-sectional study, researchers observed that trichoscopy effectively differentiates between severe and mild male pattern hair loss by identifying specific features such as yellow and white dots, vellus hair, and hair shaft diversity.

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.

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

This correspondence discusses proposed updates to the diagnostic criteria for frontal fibrosing alopecia, emphasizing the importance of differentiating it from other types of alopecia.

This study found that trichoscopy criteria can distinguish female androgenic alopecia from chronic telogen effluvium, with specific features achieving 98% diagnostic specificity.

This study found that female pattern hair loss was highly prevalent among a multiracial Brazilian population, affecting over 30% of women, and age was a significant risk factor.

This review article examines the current understanding of frontal fibrosing alopecia, noting its prevalence in different demographics and the roles of genetic and environmental factors in its pathogenesis, while highlighting that treatment approaches remain varied and lack standardization.

In this study, treatment with autologous follicular stem cells improved hair conditions in 57% of patients with androgenic and telogen effluvium alopecia, as confirmed by phototrichograms, indicating its potential effectiveness for non-scarring alopecia.

This review discusses methods to better identify unsafe donor areas in patients with diffuse unpatterned alopecia, emphasizing non-surgical management when specific diagnostic criteria are met, but reports no new clinical results.

This chapter reviews trichoscopic criteria and diagnostic features for various hair and scalp conditions, emphasizing their utility in non-invasive diagnosis, but reports no new clinical results.

This study found that adding low-dose oral minoxidil to standard treatment for lichen planopilaris was safe but did not significantly improve hair density or thickness, although minor hair regrowth was observed in some scarring areas.

Androgenetic alopecia is the only hair loss condition with specific diagnostic criteria in trichoscopy.

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.

This review discusses trichoscopic features of hair disorders in individuals with dark skin phototypes and reports no new clinical results; the authors emphasize the need for more specific diagnostic criteria for these populations.

This paper reviews Satoyoshi syndrome and suggests diagnostic criteria to differentiate its subtypes, emphasizing the importance of testing alopecia areata patients for antinuclear antibodies, muscle spasms, and diarrhea.

This article introduces a new grading system called the FPHL Severity Index to better identify and monitor early stages of female pattern hair loss using clinical criteria.

In this study, no significant association was found between the severity of androgenetic alopecia in males and trichoscopy features such as hair diameter diversity, vellus hair, and white dots, suggesting that trichoscopy may not predict alopecia severity based on the Hamilton–Norwood scale.

This case report describes areata-like lupus in a 63-year-old woman, characterized by nonscarring patchy alopecia similar to alopecia areata, without meeting systemic lupus erythematosus criteria.

This review discusses trichotillomania and traction alopecia, focusing on their clinical features, diagnostic criteria, and treatment options, but it reports no new research findings.

According to this review, frontal fibrosing alopecia in men exhibits unique clinical features and is often misdiagnosed, underscoring the need for validated diagnostic criteria and treatment evaluation.

This study observed that in a series of 28 patients with different types of alopecia, specific trichoscopic markers like exclamation-mark hairs and yellow dots helped distinguish alopecia areata from conditions like lichen planopilaris and discoid lupus erythematosus, which showed follicular ostia loss and white scarring.

This systematic review reports that trichoscopy is highly accurate for diagnosing scalp disorders, suggesting it as a valuable alternative to biopsies and supporting recommendations for its integration into routine dermatology practice.

This review covers current knowledge of tricoscopy's applications in diagnosing and monitoring scalp and hair disorders but presents no new clinical results.

This study found that certain trichoscopic features like white peripilar sign, yellow dots, and scalp pigmentation are positively correlated with the severity of androgenetic alopecia in Chinese patients.

This study examined trichoscopic findings in androgenetic alopecia, reporting that hair diameter variability, vellus hairs, and the peripilar sign are valuable indicators for diagnosing this condition.

Trichoscopy is a helpful and quick method to identify different types of hair loss in women.

In this review, researchers outline the characteristics of scalp rosacea, an underrecognized inflammatory dermatosis, describing its multifactorial pathogenesis, diagnostic features, and management strategies, noting its clinical similarities with facial rosacea and the absence of standardized diagnostic criteria or therapeutic guidelines.

In this retrospective observational study, researchers found that the Dean Scale showed better diagnostic accuracy than the CTCAE scale for detecting clinician-reported therapeutic responses to minoxidil in patients with anticancer therapy-induced alopecia, but both scales had limitations in recording clinically significant hair regrowth.

This review discusses the characteristics and diagnostic challenges of fibrosing alopecia pattern distribution, proposing an algorithm for hair transplantation, but reports no new clinical results.

This article discusses the advantages and different techniques of dermoscopy for skin lesion visualization and reviewing no new clinical results; it emphasizes the integration of polarized light and the importance of training.
