This article presents a case of spontaneous, recurrent necrotizing infundibular crystalline folliculitis in the inguinal region and suggests unknown etiology possibly linked to microbiome and sebaceous gland dysfunction.

This study reports the synthesis and structural characterization of a novel dinuclear platinum(III) complex with potential antitumor and catalytic activity.

This study identified Sciellin, a new protein precursor to the cornified envelope in keratinocytes, with unique solubility properties hinting at its potential role in envelope assembly.

This study demonstrated that mitochondrial function in keratinocytes is crucial for maintaining skin homeostasis and hair follicle development, as its impairment led to disrupted hair morphogenesis and early death in mice.

This study suggests that the cell membrane complex in hair cuticles contains hydrophilic regions with disulfide bonds allowing polymer uptake and hydrophobic lamella-like lipid layers.

This abstract describes the initial success of intralesional cidofovir for SCC treatment and states that it has not shown systemic toxicity, but it does not report new clinical trial results.

This study found that the molecular structure of hair is more sensitive to synchrotron X-ray radiation than its supramolecular architecture, indicating potential concerns for biological analyses using such radiation.

This study confirms that the proposed universal model for hard α-keratin structure applies to all known forms across various mammalian species.

In this study, researchers created nanowhiskers from crab shell-derived nanochitin that self-assembled into vibrant structural colors within a film. The material, sensitive to environmental changes, shows potential as a food freshness indicator and a sustainable dye for cosmetics due to chitin's biocompatibility.

This study identified the structures of cyclohexyl and phenyl analog impurities in finasteride using HPLC and spectral analysis.

This study found that chitin nanofibrils prepared by the aqueous counter collision process exhibited superior emulsifying properties for stabilizing oil droplets in Pickering emulsions compared to cellulose nanofibrils.

This study suggests that varying intersheet interactions may explain the differences between the two polymorphic forms of macrofibril assembly in Merino wool and hair.

In this study, the researchers found that tyndallization effectively sterilizes aqueous solutions of hyaluronic acid without diminishing their regenerative properties, and these properties remain intact even at low temperatures, supporting potential applications in cryobiology and cryomedicine.

This study found that the moisture sorption and desorption process can differentiate between cosmetic treatments of hair and provide insights into hair fibre structure changes, with bleaching causing greater symmetry breaking than perming.

This model study describes how interactions between hair keratin and various materials alter hair's physical and mechanical properties by affecting noncovalent bonds.

This study reports that expressed mouse type Ia and type IIa trichocyte keratins were successfully assembled into intermediate filaments in vitro, while also suggesting that disulfide bond cross linking enhances their stability.

This study developed an advanced HPLC-ESI-ion trap MS(n) method for the structural identification of cyclosporin A analogs CyA and CyC and reported the first MS(n)-aided identification of a new CyA analog.

This chapter discusses phase transitions in various pharmaceutical examples and does not present any new research findings.

This study clarified and quantified the concept of hair transparency using a validated mathematical model based on measurable hair properties and consumer perception data from stylists in Japan and China.

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.

Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.

This study found that the moisture content of human hair significantly influences the type of fracture under tensile loading, with low or high humidity levels leading to smooth fractures and intermediate humidity resulting in step fractures.

This study observed that surfactants in cosmetic treatments can bind to keratinous tissues like hair and nails, affecting their tensile properties and possibly leading to deterioration depending on the specific detergents used.

This study found that the extraction-resistant structures in hair, feathers, and hagfish teeth are due to ε-(γ-glutamyl)lysine cross-linked proteins, emphasizing their role in maintaining the integrity of these materials.

This study reported that gels containing methyl cellulose exhibited the highest consistency factor and optimal homogeneity compared to those made with hydroxypropyl cellulose or its combination with pullulan, indicating the significant impact of gelling agents on gel properties.

A new compound that could treat various androgen-related conditions was created and analyzed.

This study suggests that finasteride-loaded liquid crystalline nanoparticles could be a viable alternative to oral administration for treating androgenetic alopecia due to their controlled release and skin permeation properties.
