This study found inflammation and fibrosis in both pattern hair loss cases and controls but concluded that these factors may not significantly contribute to the pathogenesis of pattern hair loss.

This study found that in Pomeranian dogs with alopecia X, dermoscopic evaluations can supplement diagnoses, and transverse skin biopsy sections better assess hair follicle density and identify growth arrest phases compared to longitudinal sections.

This commentary reviews the evidence for microinflammation's role in pattern hair loss and suggests that further studies with age- and sex-matched controls are needed to substantiate the findings.

This case study reported on a 72-year-old woman initially diagnosed with inflammatory alopecia, later identified as having angiosarcoma of the scalp, revealing the importance of considering unexpected malignancies during evaluation of suspected inflammatory alopecia cases.

Clinical signs don't match inflammation levels in lichen planopilaris and frontal fibrosing alopecia.

This study found that serial vertical sectioning of scalp biopsies significantly increases the histological diagnostic yield for alopecias.

This study reports that citrulline, uniquely found in the inner root sheath of hair follicles, can be specifically detected with the carbamido diacetyl reaction, resulting in a bright orange color.

This correspondence highlights existing research on pattern hair loss, discussing findings about immune deposits, lymphocytic infiltration, and responses to treatment, and calls for future well-controlled studies.

This article reviews advances in the histologic evaluation of alopecia and hair-related disorders, without presenting new clinical results.

This study analyzed skin specimens from Australian Merino ewes to estimate hair follicle properties across different strains, providing baseline data essential for future genetic studies on fleece structure, but reported no new conclusions.

This study found that the Verhoeff-Van Gieson stain effectively distinguishes scarred from non-scarred dermis and aids in classifying types of permanent alopecia based on elastic tissue patterns.

This article discusses a new device for visualizing and quantifying skin distribution of a radioactively labelled compound, but reports no new clinical results.

This article reviews the differences between scarring and non-scarring alopecias and describes diagnostic methods but reports no new clinical findings.

This source outlines the crucial steps and techniques for conducting scalp biopsies to diagnose cicatricial and non-cicatricial alopecias, emphasizing the importance of proper biopsy site selection, technique, and specimen processing to accurately interpret histopathology and understand related hair follicle disorders.

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 study found that scalp involvement in dermatomyositis consistently shows a nonscarring pattern with chronic telogen effluvium, featuring telangiectasia and mucin deposition as universal histologic markers.

This study found that nonscarring alopecia in patients with systemic lupus erythematosus may indicate higher disease activity, as evidenced by specific histological and immunofluorescence changes.

This report provides the first microscopic description of pachyonychia congenita-associated alopecia, identifying a combination of histological features that might be unique to this condition.

This article discusses the phases and histological features of alopecia areata and reports no new clinical findings; the authors emphasize recognizing these phases for accurate diagnosis.

This review discusses histologic findings in alopecia and emphasizes the importance of understanding normal follicular anatomy and cycles in transverse sections, without reporting new results.

This study found that in Alopecia Areata, increased non-anagen terminal follicles and peribulbar lymphocytic infiltrate are consistent histological features, even in cases that have progressed to scarring.

This study found that transverse sections of scalp biopsies, particularly looking at the anagen:non-anagen hair ratio and presence of pigment casts, effectively distinguish alopecia areata from androgenetic alopecia.

Other common signs, not just the well-known immune cells around hair bulbs, are important for diagnosing hair loss from alopecia areata.

This study found that transverse sections of scalp biopsies showing lower anagen:non-anagen hair ratios and presence of pigment casts help differentiate alopecia areata from androgenetic alopecia.

This abstract presents a case of arsenical dermatitis with pigmentation and alopecia developed during treatment with arsphenamine for a positive Wassermann reaction.

This study reports an improved method for determining blood type from human hair using immunohistochemistry.

The researchers developed a technique for processing and staining free hair samples using paraffin embedded blocks, revealing that routine staining does not color the enucleated cuticle, while the cortex and medulla show distinct colorations when stained.

The document explains how hair follicles develop, their structure, and how they grow.

This study reported that combining vertical and horizontal sectioning in scalp biopsies allows for a more thorough examination of histological changes in various types of alopecia.
