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 report describes two scalp lichen simplex chronicus cases with hair loss and intense itching, noting unique dermoscopic and histopathological features.

This study reported that the treatment of hair with glyoxylic acid straighteners causes major conformational changes within the hair fiber due to interactions between carbonyl and keratin components.

This study found that the acidic hair straightening formulation at pH 1.0 improved hair alignments and straightening effectiveness more than pH 2.0, but it weakened fiber strength and affected hair color and composition.

This study found that recombinant type III collagen may aid skin aging management by promoting fibroblast proliferation and migration, with a modest impact on inflammatory marker IL-6, though it did not significantly affect TNF-a secretion in vitro.

Advanced fluorescence technology effectively treats skin discoloration from certain creams.

In this study, researchers found that a composition containing mannose-6-phosphate significantly reduced the total skin pore area by 24% in women after 56 days and by 30.2% in men after 7 days, suggesting its effectiveness in improving pore appearance by targeting dermal and epidermal modifications.

The researchers observed that in cichlid fishes with different dental structures, tooth replacement accelerated more than three times following tooth extraction, alongside distinct changes in gene expression and cellular interactions over one week, providing insights into tooth regeneration mechanisms in vertebrates.

Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.

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.

In this study, oral care products like foams and a spray, similar to tap water, improved salivary pH and oral clearance rates after exposure to Coca-Cola® in young adults, but no significant differences were found between these products and tap water.

In this study, human gingival mesenchymal stem cells responded differently to inflammation mediated by oxidized low-density lipoprotein (oxLDL) compared to cytokines; oxLDL significantly reduced cell proliferation but had less negative impact on differentiation characteristics.

This study found that certain concentrations of sodium fluoride accelerated apoptosis in cultured human hair follicles, while sodium selenite could counteract this toxicity in vitro.

In this study, the researchers found that micronizing hinokitiol using supercritical carbon dioxide impacted its particle size, with increased temperature enlarging particles and increased pressure reducing them.

This study introduced a new technique, 2Phatal, enabling precise apoptotic cell ablation in living animals, revealing unique cell-type differences in apoptosis-related dynamics.

This study developed a multifunctional TA-MoS2-SF hydrogel for diabetic ulcer treatment, demonstrating enhanced photothermal bactericidal effects, immune environment remodeling, and fibroblast proliferation, suggesting it may serve as an effective 'antibacterial-immunomodulatory-repair' strategy.

This study describes a staining technique that differentiates medullary from cortical keratin in sheep and goat hair using Ziehl-Neelsen's carbol-fuchsin in skin biopsy sections.

In this study, the researchers developed a living microecological hydrogel containing Chlorella and Bacillus subtilis that showed potential in promoting the healing of infected diabetic wounds by providing continuous oxygen delivery and anti-infective properties.

This study suggests that although hydroxyapatite gel has strong bactericidal effects, its combination with platelet-enriched blood autoplasm does not enhance antibacterial activity in endodontic treatment for chronic apical periodontitis.

This case report describes successful treatment of folliculitis decalvans in a 41-year-old woman using oral fusidic acid, leading to clinical improvement and no recurrences after six months.

The researchers reported that increasing protein content in human hair keratin/calcium alginate blend films led to larger molecular aggregates, which influenced the films' physical properties such as light transmittance and tensile strength.

This study found that the Nod factor from Rhizobium meliloti, particularly at concentrations of 10-8 and 10-7 M, induced specific membrane depolarization and root-hair deformation in Medicago sativa, depending on the stage of cell differentiation.

This study concludes that tiny infundibular cysts, rather than comedones, are the primary lesions in chloracne.

This study used infrared spectroscopic imaging and scanning electron microscopy to reveal that alopecic hair has more irregular laminated structures and differing chemical profiles than normal hair, suggesting changes related to alopecia progression.

This study found that incorporating Canavalia ensiformis lectin into alginate and carboxymethylcellulose films enhanced angiogenic factor expression, suggesting these biopolymer films could be an effective alternative for wound treatment.

This study purified trichohyalin protein from pig tongue epithelium, characterizing its unique properties and structure, which may facilitate future functional research.

In a study using mice, researchers observed that Cacumen platycladi fermented with Lactiplantibacillus plantarum CCFM1348—both as postbiotics and synbiotics—promoted hair growth, potentially by engaging the Wnt/β-catenin signaling pathway and enhancing growth factor expression.

This study found that careful light microscopy using fluid-mounted hair improves detection of the pili annulati phenotype, which varies widely in expression and affects hair fragility.
