This study found that trichoscopy was useful in diagnosing different types of alopecia, with specific trichoscopic features aiding in the differential diagnosis.

This source reports that two noninvasive tests, the pull test and a modified wash test, can help diagnose and determine the severity of different types of hair loss in women by assessing hair shedding and characteristics, offering a simple and cost-effective evaluation method.

This article reviews the complexities and challenges in hair transplant procedures, emphasizing the role of micro-inflammation and the usefulness of trichoscopy for detecting complications, and reports no new clinical results.

This study found that torsional measurements can effectively distinguish the effects of hair care products on the cuticle versus the cortex of hair fibers, unlike tensile measurements.

This review discusses the application of trichoscopy in diagnosing various hair and scalp diseases and reports no new clinical results; the authors emphasize its role as a non-invasive diagnostic tool.

This Viewpoint discusses the utility of dermoscope in routine practice and how familiarity with dynamic vs static trichoscopy may address its limitations, but it reports no new clinical findings.

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.

In this case study, a 74-year-old woman improved her scalp hair condition by reducing chronic rubbing, leading to hair regrowth without ongoing abnormalities after behavior modification.

In this study, researchers found that hair alterations such as frontal-occipital inversion in males and a high occipital hairline may aid in diagnosing the uncommon condition TRPS.

This chapter describes two simple, noninvasive methods — the pull test and modified wash test — which can diagnose and assess the severity of female hair loss, including conditions like telogen effluvium and androgenetic alopecia.

This study found that individuals with androgenic alopecia have an increased number of thin hairs (less than 40 microns in diameter) per cm², which may affect their clinical appearance.

This study found that trichoscopy has limited value for diagnosing telogen effluvium, as common findings are not specific enough to differentiate it from other conditions like androgenetic alopecia.

This case report describes a patient with lichen nitidus whose lesions improved following treatment with oral astemizole and topical steroids, although spontaneous resolution remains a possibility.

This report of four pediatric alopecia cases highlights the varied patterns and treatments, noting that differentiating alopecia from trichotillomania is crucial due to their different management approaches.

This case study describes a male patient with very late-onset trichotillomania, highlighting the condition's potential association with comorbid depression.

This study established reference values for trichoscopic parameters of hair density and thickness in healthy Indian males, providing a foundation for future research.

This review highlights the need for standardization of diagnostic techniques for hair diseases and emphasizes their importance in distinguishing conditions and monitoring treatment effects, but it reports no new experimental results.

This article provides a diagnostic guide for clinicians to differentiate between various hair shaft disorders by using a structured question-by-question approach but does not report new clinical findings.

This study found that quantitative trichoscopy is a simple and effective method for determining hair density and thickness in Egyptians, establishing baseline values for clinical hair loss investigations.

This study explores various tests that can be performed during teledermatology visits, such as self-conducted pull tests and ponytail thickness measurements, along with imaging tools, to assess hair loss virtually.

This paper highlights trichodynia as a distinguishing symptom of telogen effluvium, but it does not present new clinical findings.

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 evaluated the accuracy of the HairCheck device, a cross-section trichometer, and concluded that it effectively measures changes in hair diameter and density for assessing alopecia progression and treatment response.

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

This case report describes a 4-year-old girl with trichotillomania triggered by vitamin D deficiency, who showed dramatic improvement with vitamin D therapy.

In this study, pediatric hair and scalp disorders were effectively diagnosed using trichoscopic and light microscopic examinations, demonstrating high agreement with clinical diagnoses and emphasizing their utility as reliable, non-invasive diagnostic tools in a hospital-based setting.

This study reviews the use of trichoscopy in diagnosing and monitoring alopecia areata, highlighting that certain trichoscopic findings like yellow and black dots, exclamation mark hairs, and others, provide valuable insights into disease status and treatment response.

This case report found that vitamin D3 supplementation may improve hair growth and reduce hair-pulling behavior in patients with trichotillomania, as observed in two female patients over 3 to 4 months.

This study found that trichoscopic measurements of hair density and diameter are useful for assessing the severity of female pattern hair loss and its progression.

A new tool helps better assess and treat hair loss in Chinese men.
