This study found that the wavy coat trait in Nakano cataract mice is polygenic, involving major and minor genes, and resembles human curly scalp hair associated with the PRSS53 gene alteration.

This article reviews the molecular mechanisms involved in androgenetic alopecia and the androgen's paradoxical role in hair growth, but reports no new experimental findings.

This study investigated the molecular mechanisms of hair follicle morphogenesis in Ordos fine-wool sheep, identifying differential genes related to primary and secondary hair follicles, and providing important insights for improving wool quality and breeding strategies.

In this study, researchers used the Displacement Framework to explore how hair, especially in Black communities, serves as both a biological archive and a site of social pressure, with natural hair return symbolizing a move back to genetic origins.

This study observed that during male silkmoth development, trichogen cells in olfactory sensilla undergo significant membrane recycling, contributing to sensillum structure formation in a precisely timed series of stages.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.

This study found that the tensile strength of curly hair is influenced by two main components, with springiness (toe region) contributing significantly, unlike in noncurly hair where it is negligible.

This study hypothesizes that curly hair is shaped by the contraction of the Arrector Pili Muscle within the follicle, potentially modifiable through muscle-relaxing treatments, but further research is needed to confirm this mechanism.

This study found that pigmented vellus and upright regrowing hairs are the only predictive trichoscopic markers of hair regrowth in patients with alopecia totalis and universalis.

Crickets have genetically controlled hair plates that help them sense and move their antennae.

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 reports that aging in mice leads to curved hair follicles and an increase in white hairs, potentially due to changes in keratinocyte and melanocyte stem cells.

In this study, individuals with a c.1072C > T mutation in the EDAR gene showed more hair shaft deformations compared to non-mutation carriers, highlighting EDAR's role in hair follicle development.

This study suggests that the outermost hair cuticle surface is rich in 18-methyleicosanic acid (18-MEA), supporting previous findings of its multilayer lipid and protein structure.

QIA-64 software can measure straight wire lengths accurately but needs improvement for curved wires and width measurements.

This study reported that the coat hairs of golden takin, living in harsh environments, have unique structural features compared to cattle, with overcoat hairs having continuous medullated tissue and undercoat hairs being finely crimped, potentially contributing to temperature regulation in cold conditions.

This case study suggests that patients with acquired progressive kinking of the hair may benefit from finasteride treatment due to an increased risk of developing androgenetic alopecia.

This review explores the complex interrelationships among different properties of natural hair fibers and underscores the need for a holistic taxonomy to improve data interpretation across disciplines, but it reports no new experimental results.

This study suggests that the presence of more than six vellus hairs in the frontal scalp at 20-fold magnification can be an additional criterion for diagnosing early female pattern hair loss.

This study investigated the mechanical response of the human hair cuticle to strain and found that cuticular deformation directly corresponded with fiber elongation, revealing significant molecular-level changes in disulfide crosslinks but maintained structural stability, highlighting the role of the cuticle in stress resistance.

This review explores genetic and lifestyle factors influencing hair diversity and reports no new findings, calling attention to the potential for future discoveries in genetic and epigenetic research.

This study found that keratin intermediate filaments in the hair of GAN patients are altered, showing decreased diffraction signals and increased stiffness, strength, and extensibility.

This article discusses a hypothetical model of androgenic hair trichophore composed of various chemical components, but it reports no new empirical findings; the authors emphasize the model's potential impact on hair cosmetics.

This chapter reviews the chemistry of keratin fibers, which are essential for understanding the structural stability and functionality of mammalian hair and other similar biological materials.

This study explores the neurobiology and genetics of barbering (hair and whisker biting) in laboratory rodents, and its potential links to stress, aggression, grooming, and stereotypic behaviors, highlighting its significance in experimental work with these animals.

This study characterized the hair follicle patterns of Indian bison, Black buck, and Nilgai, providing valuable data to help identify these endangered species' skins, commonly targeted by poachers.

This case report describes a 50-year-old Kashmiri woman with plica polonica, detailing trichoscopic findings of entangled hair with crisscrossing shafts and concretions.

This abstract provides a directed acyclic graph of the association between chest hair amount and prostate cancer, highlighting variables and potential confounders, but it reports no new research findings.

This case report describes a hybrid cyst in a Sprague-Dawley rat, showing both infundibular and matrical differentiation similar to different parts of normal hair follicles.
