This review discusses the role of immune responses, especially Th1 cytokines, in alopecia areata pathogenesis and reports no new research findings.

This study observed that aromatase inhibitors caused hair loss in menopausal women with breast cancer, mimicking male pattern baldness rather than female androgenetic alopecia.

In this experimental study, there was no impact of the surrounding ferromagnetic film on the magnetization reversal processes in submicrometric antidot arrays, though a significant increase in coercivity was observed.

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

Two women lost hair after mesotherapy for hair loss, with one having permanent and the other temporary hair loss.

This review summarizes trichoscopic features for diagnosing common hair loss disorders and reports no new clinical results, emphasizing their diagnostic utility in conditions like alopecia areata and trichotillomania.

Dermatoscopy helps track scar changes and guide treatment.

In this study, reflectance confocal microscopy was used to diagnose periorificial dermatitis, revealing specific skin changes such as hair follicle dilatation, increased vascular density, and inflammation, which help distinguish it from similar conditions.

This review discusses how trichoscopy, a hair and scalp examination method, helps in diagnosing various hair diseases by identifying specific structural features but provides no new clinical findings.

This study reported that imaging characteristics of sebaceous nevus vary significantly by age group, revealing dynamic developmental changes that can be effectively identified through dermoscopy and reflectance confocal microscopy, offering noninvasive diagnostic potential.

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

This study found that dermoscopy can be a useful tool for diagnosing androgenetic alopecia, particularly in determining hair diameter diversity as an essential feature in Asian populations.

Dermoscopy quickly and accurately diagnosed a rare hair disorder in a 12-year-old girl.

This study reported that dermoscopy can aid in distinguishing secondary syphilis from other skin conditions by enhancing diagnostic accuracy, though there are no standardized criteria; further research is needed to confirm these findings.

The researchers observed that dermoscopy is valuable for assessing acne scars and their response to treatment, with shorter-duration scars responding more effectively.

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 study established standard trichoscopy norms for adult white females, providing benchmarks for hair thickness, percentage of thin hairs, and pilosebaceous units with single hair across different scalp areas.

This study suggests that trichoscopy with a handheld dermatoscope may help differentiate temporal triangular alopecia from other localized alopecia by identifying specific hair features.

This study suggests that trichoscopy may assist in diagnosing pemphigus, particularly for scalp-specific lesions, by identifying certain characteristic features.

In this study, trichoscopic features aiding differential diagnosis of alopecia in Korean patients were found to be similar to those in Caucasians, but pigment pattern frequencies differed due to racial characteristics.

This study found that the modified wash test was generally more effective than TrichoScan® for diagnosing hair loss, particularly telogen effluvium, though both methods showed only fair concordance with clinical diagnosis.

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 study found that oral finasteride increased the total number of hairs in men with androgenetic alopecia by 55% over 2.5 years, but did not reduce the number of miniaturized vellus hairs.

This study found that the TrichoScan software effectively differentiated between androgenetic alopecia and telogen effluvium in women with diffuse hair loss, aligning with clinical diagnoses.

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 that dermoscopy is increasingly accepted among Taiwanese dermatologists, with its use more common among women, younger practitioners, and those with dermoscopy training.

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 case report indicates that trichoscopy may significantly improve the diagnosis of Netherton syndrome by noninvasively identifying typical hair abnormalities without the need to pull hair.

This case study described the diagnosis of a trichofolliculoma in a 56-year-old woman, emphasizing its dermoscopic features and histological aspects that confirmed the tumor type, with no recurrence observed after excision.

This review examines the literature on dermatoscopy in aesthetic medicine, explores training supply and demand, and analyzes its adoption and use among professionals, without reporting new clinical findings.
