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 described a Scottish family with hidrotic ectodermal dysplasia featuring variable symptoms such as hypo/oligodontia, thin hair, and heat tolerance, and concluded they exhibited overlapping traits with Clouston syndrome.

This article discusses recent findings on piedra infections in hair and their keratinolytic activities, but reports no new clinical results.

In this study, researchers analyzed hair from different regions of Malvi cattle and found significant variations in color, shape, and band pattern, although the medullary index remained consistent between 0.50 and 0.60 across the samples.

This study suggests that elevated copper levels in domestic tapwater, exacerbated by its aggressive properties, likely contribute to green hair by damaging the cuticle and increasing copper uptake.

This study reported that there are no standardized guidelines for managing testosterone-induced acne vulgaris and androgenic alopecia in transmasculine or non-binary individuals undergoing gender-affirming hormone therapy, highlighting gaps in dermatology trainees’ preparedness to care for this population.

This source does not report study results but describes the mission and peer review process of the Biomedical Journal of Scientific & Technical Research, emphasizing its focus on genetic, biomedical, and remedial research with technical knowledge integration.

This study reported that defects in the hair cuticle were found in every case of major structural hair abnormalities examined.

This study describes a distinctive form of ichthyosis characterized by abnormal epidermal differentiation mainly within hair follicles in four patients with congenital follicular hyperkeratosis.

This study observed unique ultrastructural changes in a 4-year-old girl with pili trianguli et canaliculi that may affect hair shaft surface characteristics due to inner root sheath alterations.

The study found that pili bifurcati causes hair to intermittently split into two branches, each with its own outer layer.

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.

The researchers reported that identifying specific hair shaft abnormalities is crucial for distinguishing patchy/plaque mycosis fungoides from psoriasis and eczematous dermatitis on non-scalp skin using dermoscopy.

This study found that DHHC13 is crucial for hair anchoring and skin barrier function, with its deficiency in Zdhhc13(skc4) mice leading to cyclic alopecia and skin abnormalities due to cornifelin deficiencies.

This report describes two cases of aplasia cutis congenita with hair collar signs and hemangioma, which may suggest neural tube defects, although imaging showed no bone or neural tissue abnormalities.

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

This case report describes a six-year-old girl with hypertrichosis cubiti, characterized by excess terminal hair growth around the elbows, and notes treatment with over-the-counter depilatory creams and shaving to address aesthetic concerns.

This study described specific skin and hair follicle abnormalities in three Japanese patients with Cantu syndrome, which may relate to the regulation role of SUR2 in hair follicle growth.

This chapter reviews the clinical and morphological diagnostic features of various hair dysplasias, including atypical pili torti, pseudomonilethrix, and trichothiodystrophy, and reports no new results.

This study reports pseudopili annulati in a dark-haired Chinese girl, identifying the unique appearance and structural characteristics of her hair without finding abnormalities in the cuticle and cortex.

Cathepsin L deficiency causes hair and skin issues in mice.

This case report describes a 16-year-old with ectrodactyly-ED-clefting syndrome, where scarring alopecia with follicular involvement appeared during puberty, possibly due to anatomic hair abnormalities.

This report describes a rare case of a woman with keratosis follicularis presenting with extensive alopecia and nail abnormalities, adding to the medical literature due to its unusual presentation.

This chapter reviews various skin disorders classified as Mendelian disorders of cornification and reports no new clinical findings, highlighting the complexity of genetics involved in inherited ichthyoses.

This study found that Hoxc13 mutations in mice cause defects in hair, nail, and tongue structures, with the most noticeable issue being brittle hair leading to alopecia.

Isolated patchy heterochromia with pili annulati can occur without other health issues.

This report describes a patient with trichothiodystrophy exhibiting both specific hair abnormalities and developmental delay, contributing to the understanding of this rare disorder's clinical presentation.

This study reports an abnormal onion-shaped swelling on the hair shafts of some Abyssinian cats, affecting the appearance of their coat, though skin and hair structures appear normal under the microscope.

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 report describes a rare case of hair and nail ectodermal dysplasia in a 3-year-old girl, where treatment with topical minoxidil resulted in minimal improvement after 12 months.
