This study found that brindled mottled mice, a model of Kinky hair syndrome, exhibited abnormal development of catecholamine neurons, with increased TH-immunoreactive neurons and altered neurochemical profiles compared to controls.

This study observed that male and female androgenetic alopecia share similar trichoscopic characteristics, such as hair shaft thickness heterogeneity and increased thin and vellus hairs.

This report describes a case study of a 23-year-old female exhibiting multiple trichodiscomas, a type of benign tumor of the hair follicular discs common in familial cases and potentially linked to Birt-Hogg-Dube syndrome, though genetic testing was not performed due to financial constraints.

In this study of dogs with mucocutaneous lesions caused by various dermatological conditions, the researchers observed notable changes in haemato-biochemical parameters and trichographic features, including anaemia, elevated platelet counts, and significant telogen phase hair involvement.

In this case report, a 9-year-old horse was diagnosed with alopecia areata contributing to Malassezia dermatitis, involving lymphocyte infiltration and symptoms consistent with yeast presence.

In this study, chronic zinc chloride administration in mice led to the replacement of long coarse hairs with short fine hairs, while overall skin histology remained normal.

This article reviews various skin changes and conditions during pregnancy, noting that while many are normal, some can become pathologic, but it reports no new research findings.

This study identified a marked reduction in melanin in the hair of Yorkshire Terriers with Colour Dilution Alopecia and proposed a new pathogenetic mechanism based on these observations.

This study reports that two mouse models of scarring alopecia exhibit similar patterns of hair loss progression despite histological differences in inflammatory cell localization and MHC class I expression.

This case report describes a six-month-old infant with focal scalp hair heterochromia and no detectable underlying abnormalities, which was still present at a one-year follow-up.

This study observed that darker hair is typical in wetter regions for the Indriidae family, while within Propithecus, dark black hair is common in colder forests, suggesting evolutionary adaptations to environmental pressures.

The authors reviewed cases of six children with both hair-shaft abnormalities and neurological disorders, noting that such hair defects may indicate neurological conditions, including potentially treatable metabolic errors.

This study found that yellow dots, black dots, exclamation mark hairs, broken hairs, and nail changes observed through dermoscopy are related to the severe form of alopecia areata.

This study found that medullary cell content in mammal hair evolves from an amorphous form to a biphasic phase, with human and anthropoid hair containing both macrofibrils and microfibrils.

In this case report, a white man with mental retardation and suspected sensory neural hearing loss experienced resolution of cystic lesions and partial regeneration of facial fat after 1.5 months of pimozide therapy.

In this case study, a 38-year-old woman with monilethrix, a hair shaft disorder causing hair fragility, was also diagnosed with androgenetic alopecia, leading the authors to emphasize the complexity in diagnosing and managing such combined hair conditions.

This case report describes a 3-year-old male with X-linked ichthyosis and associated neurologic abnormalities, identifying an unusual cortical development malformation and suggesting that abnormal hair banding may assist diagnosis.

This study identified a mutation in the KRTHB6 gene in two monilethrix families of Indian origin, linking specific genetic variations to different severities of hair defects within the families.

This review explores hair signs related to nutrition disorders, such as thin and dyspigmented hair, without presenting new clinical findings; the authors highlight unknowns regarding underlying causes.

This study found that mutations affecting hair keratin expression on Chromosome 15 in mice may cause altered hair and skin features similar to other known mouse mutations.

This study found that while many drugs are reported to cause hair color changes, substantial evidence supporting a true relationship exists mainly for chloroquine and certain cancer chemotherapeutic agents.

This case report describes the first observed cytologic changes in gynecomastia associated with finasteride therapy, emphasizing that cytoplasmic vacuolization should not be mistaken for malignancy.

This case series describes seven distinct hair shaft disorders, highlighting the importance of accurate diagnosis since these conditions are often treated incorrectly as alopecias without improvement.

This review reports that nail changes such as onycholysis, thin nails, and brittleness are associated with thyroid disorders, highlighting their importance in the early diagnosis of these conditions.

This case report presents a 14-year-old girl with both type I diabetes and monilethrix, detailing her symptoms and treatment with topical minoxidil, while exploring a possible genetic link between the conditions.

This study investigated the skin of 12 Baikal seals and identified two main skin pathologies potentially linked to global warming and changes in Lake Baikal's ice regime, including koilocytosis and inflammation associated with a possible viral pathogen.

This review discusses the histopathology of male-pattern baldness and highlights ongoing disputes over several aspects, including sebaceous gland size and follicle loss, reporting no new clinical findings.

This case study describes a young woman with a unique syndrome combining lamellar ichthyosis, neuroectodermal and mesodermal defects, and hair with trichoschisis and low sulfur content.

This study found that inhibiting 5α-reductase in molluscs provokes a specific shell morphology, suggesting gastropods might have unique 5α-reductase substrates absent in vertebrates.

This review discusses the diagnosis and treatment of pityriasis rubra pilaris and reports no new clinical results.
