This review outlines the clinical and histopathological features that aid in classifying tumors arising from the folliculosebaceous apparatus and reports no new research results.

This review highlights that microscopic analysis of human scalp hair remains crucial in forensic science for crime scene investigations, despite limitations such as subjectivity and potential misidentification, and notes that integrating DNA analysis and digital imaging could enhance accuracy.

This review discusses the genetic disorder, monilethrix, characterized by fragile, brittle hair and its inheritance patterns, and reports no new clinical results.

This study examined the microscopic characteristics of hair or feather in five animal drug components of the Shenrongbian pill, identifying distinctive medulla cell shapes and hair cuticle patterns for each component.

This study found that peripilar signs on the scalp are linked to perifollicular lymphocytic infiltrates in early androgenetic alopecia, detectable even in areas with high hair density.

This study observed that Japanese women experience diffuse central hair loss after age 40, characterized by reduced hair density and thicker hair ratio rather than vellus-like hairs.

Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.

This research retrospectively evaluated 92 skin specimens to propose histopathological criteria for diagnosing alopecia areata incognito, distinguishing it from telogen effluvium and androgenetic alopecia.

The document describes a woman with familial Parkinson's disease due to a genetic mutation, showing severe symptoms and poor response to treatment, and suggests finasteride may help reduce symptoms in Tourette syndrome.

This review discusses the role of hair microscopy in diagnosing alopecia, stating that while it excludes diagnoses related to hair breakage, it only confirms nonspecific short anagen in alopecia cases.

This review discusses the histologic features of nonscarring alopecia and highlights the importance of clinical-pathological correlation for accurate diagnosis, but reports no new clinical results.

Polarized microscopy is a quick and free method to correctly identify types of hair loss.

This study documented that dermatophytosis was highly prevalent in Basra's cats, particularly affecting males and cats under nine months, with lesions most frequent on ears, face, and abdomen.

In this study, researchers administered Trigona bee honey to dogs with dermatitis and observed improvements in skin damage, including reduced inflammation, decreased erythema, and increased hair growth at alopecia sites, indicating its potential as a treatment for canine dermatitis.

This paper discusses the use of Digital Volumetric Imaging with fluorescent dyes to visualize and compare the interior structures of six different virgin hair types, reporting no new clinical results.

This study found that patients with myotonic dystrophy types 1 and 2 often exhibit skin abnormalities, which correlate with genotype severity and serum vitamin D levels, and suggest premature aging.

The authors concluded that dermoscopy is a useful tool in diagnosing different types of hair loss and scalp conditions.

This study found that a peripilar white gray halo around hair emergence is a highly specific and sensitive dermatoscopic feature for diagnosing central centrifugal cicatricial alopecia in African American patients with mild central thinning.

This paper reports on the structural characteristics of α-type filaments in the inner root sheath cells of guinea pig hair follicles without presenting new clinical findings.

This study reports a good correlation between the curvature of human eyelashes and the displacement of the neutral axis, influenced by the non-uniform thickness of the outer cuticle layer.

In this case report, narrowband-UVB phototherapy successfully treated a rare instance of Graham Little-Piccardi-Lassueur syndrome, a variant of lichen planopilaris, as investigated through non-invasive imaging techniques.

This review examines the use of dermoscopy for diagnosing common hair disorders and highlights its importance, but it does not report new clinical results.

This Delphi consensus study provides expert insights into hair aging, aims to enhance diagnostic precision and management of age-related hair changes, and identifies possible new therapeutic targets.

This article reports electron microscope studies on the structure of hair and wool, but it does not present new clinical findings.

This review discusses the development and application of multiphoton microscopy in dermatology, highlighting its advantages and potential future research directions without reporting new clinical results.

This study identified the presence of apoptotic or necrotic keratinocytes and hair shaft dystrophy as potential markers of hair loss in patients with HIV-1 infection.

This study found that trichoscopy can rapidly and noninvasively diagnose tinea capitis and alopecia areata in pediatric patients by identifying specific hair patterns associated with each condition.

Reflectance confocal microscopy can tell apart white dots on the scalp as either sweat gland ducts or hair follicle openings.

This study found that aging in Korean individuals is associated with changes in hair diameter and surface structure, as observed through atomic force microscopy.

This study introduces a five-modal microscopy technique that allows label-free, in vivo observation and quantitative analysis of various wound healing processes.
