This study identified trichohyalin as an early differentiation marker in hair follicles, with potential structural roles related to alpha-helical formations, based on the partial characterization of its cDNA in sheep.

This study identified distinctive trichoscopic features that may aid in diagnosing loose anagen hair syndrome, such as rectangular black granular structures, solitary yellow dots, and a predominance of follicular units with single hairs.

In this hospital-based observational study involving 30 participants, researchers found no statistically significant difference in the force needed to pluck anagen versus telogen hair in the frontal and occipital scalp regions of women with female pattern hair loss.

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 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.

In this study of a TRPS type I patient, many genes related to keratin and hair development were down-regulated in balding scalp areas, providing new insights into TRPS and hair morphogenesis.

This review highlights the light microscopic features of various infectious and non-infectious hair conditions and reports no new clinical results.

This case report highlights how trichoscopy enabled the diagnosis of androgenetic alopecia in a woman experiencing diffuse hair loss, emphasizing its utility as a diagnostic tool.

This observational study reports that a TRASER device using specific wavelengths for vascular and follicular targets showed both clinical responses and histological changes, suggesting its potential as an effective vascular and hair removal tool.

This case study suggests that trichoscopic examination of the beard can aid in diagnosing frontal fibrosing alopecia in men, especially when challenging to differentiate from androgenetic alopecia.

This study, examining perceptible hair density changes in androgenetic alopecia patients, found that dermatologists could accurately detect hair loss at a lower threshold than previously noted, specifically at a 22.66% relative density difference, challenging assumptions about their predictive accuracy based solely on clinical examination.

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.

This letter discusses congenital triangular alopecia (TTA), a non-scarring hair loss condition often seen in children, without reporting new clinical findings.

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.

This study suggests that clinically apparent fragile hair in children is rarely linked to trichothiodystrophy, and the tiger-tail pattern is not wholly specific to this diagnosis.

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 photoepilation using intense pulsed light significantly reduced hair growth parameters, and phototrichograms may offer an objective method to evaluate its effectiveness.

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 article discusses current visualization methods for assessing hair restoration therapy responses, noting imprecision in triangulated measurements and patient dissatisfaction with visible tattoos.

This study found that the TrichoScan effectively measures hair growth changes, showing significant increases in hair counts and thickness in men with androgenetic alopecia after 6 months of using 5% minoxidil solution.

This study observed that hair density and growth rates vary by location and age, and the presence of thin hairs predominates in younger women with mild patterned hair loss.

This study evaluated dermoscopic findings in patients with different types of primary cicatricial alopecias, suggesting trichoscopy may aid in differential diagnosis by revealing abnormalities in scalp structures.

This study shows that multiphoton microscopy can non-invasively distinguish scarring from non-scarring alopecia by identifying specific morphological features in hair follicle structures.

This study identified five distinct scalp whorl patterns, noting that white males have the most distinct whorls, while African Americans and women more often exhibit a diffusion pattern.

This article reviews the historical development of trichology and proposes the term "trichiatrist" for physicians specializing in the medical treatment of hair and scalp, noting no new clinical findings.

This study found that dermoscopy can identify distinctive features in canine pattern alopecia, such as hair shaft thinning and pigmentation patterns, which may aid in diagnosing this and potentially other skin disorders.

In this study, ultrasound showed promise in differentiating trichilemmal cysts from epidermoid cysts, suggesting potential value for clinical management.

This study identified five distinct natural scalp whorl patterns and noted that White males have more distinct whorls, whereas African Americans and women often display a diffusion pattern.

In this study, researchers observed that trichocytic and epithelial cytokeratins have distinct expression patterns within various human and bovine hair follicle cells, contributing to understanding hair follicle development and growth.
