This study found that spermidine, a polyamine, plays an essential role in hair growth in sheep follicles, while spermine is not required for normal follicle function.

This study found that keratin intermediate filaments in the hair of patients with giant axonal neuropathy were structurally altered, resulting in hair that was stiffer, stronger, and more extensible.

A bald man grew hair on his head after taking a drug called diazoxide, but lost it again when he stopped the medication.

This study suggests that residues Val-889 and Arg-752 in the androgen receptor's steroid binding domain are crucial for NH2-/carboxyl-terminal interaction, affecting receptor stability and function.

This study found that hydrophilic carbon dots (Lys-CA-CDs) induced bovine serum albumin to form more wormlike fibrils, while inhibiting hen egg white lysozyme from forming hair-like fibrils.

This study suggests hair diameter may indicate protein status in children if the sampling location on the head is controlled, noting inconsistencies in past research.

This article reviews a tabletop microscopy method for recording electromagnetic radiation from tissues, using hair follicles as a model, and presents no new clinical findings.

This review discusses pyrene excimer nucleic acid probes for detecting biomolecules and protein-DNA interactions and reports no new experimental findings.

In this study, several dermoscopic features such as hair diameter diversity, brown peripilar sign, and focal atrichia were frequently observed in both male and female androgenetic alopecia patients, highlighting these as potential AGA indicators.

This study found that, compared to oxidative treatments, reductive perm-waving more severely impacts the intermediate filaments in European human hair, while both treatments alter denaturation kinetics in a first-order manner.

This review examines the effects of various factors on the molecular and nanostructural ordering of human hair, highlighting its potential as a diagnostic material for environmental and public health monitoring, but reports no new experimental results.

This study identified two novel point mutations in the hHb6 gene associated with monilethrix, suggesting these mutations could serve as diagnostic markers for this genetic hair disorder.

This case report describes a patient with adrenomyeloneuropathy, highlighting unusual MRI findings of high signal areas in the right striatum.

In this study, researchers used Raman spectroscopy to identify melanin-specific features in mouse hair as potential biomarkers for gamma-radiation exposure, achieving a sensitivity of 88% and specificity of 83%, with classification accuracy declining over time beyond 7 days post-irradiation.

This case report describes a 3-year-old boy with trichothiodystrophy, highlighting specific MRI findings of diffuse dysmyelination and osteosclerosis that may be unique to the disorder.

In this study, an ammonia-free and PPD-free permanent hair dye was tested on 50 ethnically diverse females, showing no cases of contact dermatitis and significant improvements in hair shine, color, moisturization, porosity, and combability after two dyeing sessions.

This study introduced a novel graphene-based hair dye that is non-reactive, non-invasive, and eliminates toxic chemicals, while providing durable color, antistatic properties, and efficient heat dissipation, even after 30 washes.

This study found that overlapping concentration imbalances of metals and proteins could provide new insights into the pathophysiological mechanisms of bipolar disorder and schizophrenia, highlighting ongoing oxidative stress and inflammation in both diseases despite treatment.

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.

In this study, EDA-A2 transgenic mice exhibited multifocal myodegeneration dependent on XEDAR, suggesting a potential role for XEDAR in skeletal muscle homeostasis.

This study reported that the calculated and experimental electronic and vibrational properties of minoxidil were in good agreement, providing detailed insights into its molecular structure and thermal behaviors.

This study assessed whether the elemental composition of human hair could serve as a marker for kidney stones, cholelithiasis, hypertension, and diabetes, but it reports only variations in element content along hair regions.

This study found that polarized light microscopy is more effective than diffractive microscopy in distinguishing scarring from non-scarring alopecia, providing a highly specific adjunct diagnostic tool for alopecia biopsy specimens.

This study found that Finasteride may spontaneously diffuse into an SDS-based model cell membrane at a significant rate, with distinct behavior in polar and non-polar solutions.

This study used nanoscale secondary ion mass spectrometry to locate where calcium and copper are concentrated in colored hair, finding these metals particularly in the cuticle's sulfur-rich regions.

This study observed that DMAP scaffolds in a full-thickness wound model promote dermal appendage regeneration by activating humoral immunity, specifically through B cell activation and antibody production, even when adaptive immune cells' infiltration is restricted.

This study found that a synthetic polyphenol, dimeric 1,2,4-benzenetriol (diBTO), can coat gray hair and gradually oxidize, creating a resistant brown layer similar to apple browning, which offers a practical hair dyeing solution that withstands washing and reduces the need for long dyeing sessions.

This study explored the use of manganese-doped calcium silicate nanowire-incorporated alginate hydrogels (MCSA hydrogels) for treating melanoma and promoting wound healing, finding that these hydrogels effectively ablate melanoma under near-infrared irradiation and enhance vascular endothelial cell activity for tissue regeneration.

This study found that Alaskan moose hair mineral content varied seasonally and by location, with differences in magnesium, copper, and manganese levels linked to winter-killed calves.
