A teenager's hair with alternating white and dark bands, known as Pili annulati, is a genetic condition that is usually harmless and often considered attractive.

This report describes a case of two sisters with kinky, tangled hair diagnosed using trichoscopic and microscopic methods; they were treated with topical minoxidil.

This paper introduces an algorithm for using smart device-mounted microscopes to analyze scalp images and diagnose hair loss by extracting specific hair loss features.

This case report identifies an association between trichothiodystrophy and a urologic malformation with primary hypercalciuria, adding to the spectrum of TTD-related abnormalities.

This study found that mink pelts with "singe" and "red hip" defects often exhibit split hair tips and altered cuticle structures, which may contribute to their undesired metallic sheen.

This study observed that dermatophytosis, primarily caused by fungi like M. canis, is the most common fungal skin infection in cats, often resolving spontaneously except in young or immunocompromised animals.

This study highlights that dermatophytosis, a common fungal skin infection in cats, caused by Microsporum and Trichophyton species, typically resolves on its own but may be more severe in immunocompromised individuals and young animals.

This study explores the physical properties of hair from various wild mammalian species using polarized light microscopy, aiming to correlate these properties with the internal structures such as the medulla, cortex, and keratin cuticle.

This study observed that the pig integument is similar to human skin in both light and electron microscopy, with minimal postnatal developmental differences noted.

This article illustrates various hair shaft defects and suggests that dermatologists can diagnose most of them using light microscopy and polarization without needing advanced imaging techniques.

This study found that optical coherence tomography provides highly reproducible and less variable measurements of hair shaft thickness compared to standard light microscopy, offering a promising noninvasive tool for clinical practice.

This study reported that hair microscopy can help diagnose rare pediatric neurological diseases, as specific hair characteristics were linked to conditions like giant axonal neuropathy, Griscelli syndrome, and Menkes disease.

This study used Scanning Electron Microscopy to analyze South American mummy hair, revealing high levels of sulfur, calcium, and potassium, highlighting SEM's utility in anthropological investigations.

This study suggests that using a dermoscope, a handheld microscope, can effectively help distinguish between Pityrosporum folliculitis and Acne vulgaris by revealing unique lesion characteristics that are not visible to the naked eye, offering a practical diagnostic alternative when KOH examinations are unavailable.

This paper discusses the use of dermatoscopy as a fast, noninvasive technique for diagnosing hair shaft disorders and reports no new results; the authors highlight its advantages over traditional microscopy methods.

This article reports a case of trichothiodystrophy in a 7-year-old girl with sulfur deficiency in her hair, characterized by sparse, slow-growing hair and distinctive tiger tail banding under microscopy.

This study found that horses with inflammatory skin diseases had a higher prevalence of surface cocci and fungal poroconidia compared to those with healthy skin.

This study reports that structural abnormalities in the inner root sheath of hair follicles may cause the hair shaft to be loosely attached in patients with loose anagen hair syndrome.

This study details the histological structure of the white domesticated pig's ear skin and discusses its relevance as a model for human dermatological research.

This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.

This study examined prenatal and postnatal development of rat skin, observing marked changes in epidermal thickness and collagen fiber distribution as the rats aged.

This study found that the vermilion border and mucosa of the monkey lip have a dense sensory innervation, which correlates with their known tactile sensitivity.

This study concluded that epidermal growth factor may induce a 'catagen-like' phase in human hair follicles by disrupting normal cellular proliferation and migration patterns.

In this study, the authors observed that cell-mediated immune mechanisms may be involved in the pathogenesis of benign follicular mucinosis, based on the cellular and immunological characteristics of two patient cases.

This article reviews various hair abnormalities observable through trichoscopy in conditions like monilethrix, trichorrhexis nodosa, and ectodermal dysplasias, with no new clinical findings reported.

This study identified a novel KRT86 mutation associated with autosomal dominant monilethrix, expanding understanding of its genetic basis beyond known motifs.

This report identified longitudinal grooves in the hair shafts of four children, diagnosing them with uncombable-hair syndrome.

This correspondence describes the dermoscopic features of an osteonevus of Nanta but does not report new clinical findings.

This case report describes a 32-year-old man with therapy-resistant acneiform eruptions later diagnosed as vellus hair cysts, emphasizing the condition as a potential diagnostic consideration in similar cases.

This article reports a case of a 19-month-old boy with scalp erythematous papules and hair loss, showing no improvement with initial treatment.
