This study found that stepwise thermal treatment of human hair waste at temperatures from 200 to 450 °C produced hollow microtubes, with structure changes influenced by temperature, core degradation, and cortex melting.

This study found that cultured hair apparatus cells initially showed low keratin antibody reactivity, which increased by day 6 as cells differentiated and corresponded with electron microscopic observations.

In this study, researchers found that an ethyl acetate extract of the green microalga Scenedesmus deserticola significantly increased the viability of human dermal fibroblasts by over 20% compared to a control and identified a potent anti-UV compound, loliolide, through further fractionation.

This study reports that hair fibers degrade most in acidic sandy clay, while silicone oil treatment is effective for conserving various hair types and artifacts.

This study provides conclusive evidence of exogenous calcium fatty acid deposits forming between the cuticle layers in hair, affecting its optical and mechanical properties.

In this study, the combination of Poly-D,L-Lactic Acid and Platelet-Rich Plasma was reported to be effective for improving wrinkle severity and skin brightness in a 45-year-old woman.

This study developed and tested a new injectable hydrogel for chronic diabetic wounds, reporting significant improvements in wound healing through enhanced angiogenesis, epithelization, and reduction of inflammation and infection in animal models.

This review summarizes recent pathological discoveries related to chemical leukoderma and chemical-induced vitiligo, especially focusing on rhododendrol, a chemical responsible for a significant outbreak affecting around 20,000 individuals in Japan and Asia.

This study found that chemically treated hair, particularly when subjected to both acid straightening and bleaching, experiences more significant structural damage when exposed to heat, highlighting key changes in both the internal and surface components of hair fibers.

In this study, autophagy was commonly observed during keratinization in neonate rat hair follicles, suggesting lysosomal proteases and cytoplasmic enzymes may coordinate in hair follicle cell differentiation.

Hair fibers may have a unique, non-protein sheath not previously identified.

PP405 may help hair growth by activating hair follicle stem cells.

This study found that RALF peptides, through liquid-liquid phase separation, form condensates with pectin and other proteins, playing a pivotal role in plant development and stress response regulation.

This study found that inhibiting arachidonate 12-lipoxygenase (ALOX12) may enhance hair cuticle maturation by increasing S100A3 protein citrullination and promoting cuticular differentiation in isolated human hair follicles.

In this study, injecting Nε-(carboxymethyl) lysine into skin tissue weakened hair shaft and follicle formation, likely by inhibiting cell proliferation and migration needed for hair follicle morphogenesis.

This study observed that processing techniques such as degreasing, bating, and tanning influence mink skin by altering the distribution of fat glands and collagen fibers, potentially impacting hair follicle structure and mink product quality.

In this study, the researchers optimized a method for culturing melanocyte precursors from hair follicles and found that 1,25-dihydroxyvitamin D3 significantly promotes their differentiation and melanin synthesis.

This study found that chemically modifying hair with 2-iminothiorane hydrochloride improved the permanence of hair setting without damaging the hair by increasing disulfide bonds.

This study describes a gel-supported in vitro system for culturing skin samples that may effectively replace animal systems for toxicity testing, showing high correlation with in vivo skin toxicity measurements.

In this study, researchers found that stabilizing the protein HIF1A in hair follicles promotes glycolysis over oxidative phosphorylation, potentially reducing oxidative stress and supporting hair growth.

This study investigated the effects of heat-treated Limosilactobacillus fermentum LM1020 on hair growth and reported increased hair density, improved cellular activity, and beneficial scalp microbiota changes in patients with androgenetic alopecia over 24 weeks.

This study found that cyclophosphamide induced significant keratinocyte apoptosis in anagen hair follicles of mice, while topical calcitriol-analogs reduced this apoptosis, suggesting a protective effect against chemotherapy-induced alopecia.

This study found that acne lesion formation involves early hyperkeratinization and inflammation around hair follicles, creating a self-sustaining cycle that may progressively worsen acne.

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 found that 5-aminolevulinic acid combined with ferric ammonium citrate stimulated hair follicle growth and induced hair-like structures in human hair follicle models, suggesting its potential as a treatment for hair loss.

This study found that conditional deletion of Mof in mice resulted in severe defects in skin development, including compromised epidermal differentiation and hair growth, leading to perinatal lethality.

This study found that L-cystine, D-pantothenat, and miliacin can enhance the metabolic capacity and proliferation of human keratinocytes, with a combination of these additives potentially providing synergistic benefits in growth media.

This study demonstrated that hair relaxers containing common chemicals significantly reduced cell viability and increased apoptosis in human skin cells, suggesting potential toxicity that could be assessed with advanced in vitro technologies rather than animal testing.

In this study, researchers observed that Malassezia species show different lipid metabolism and growth patterns depending on pH, with slightly acidic conditions promoting beneficial lipid bio-conversion for skin health, while neutral pH resulted in lower growth and lipid content, potentially negatively impacting the skin.

This study observed that bleaching brown human hair with persulfate salts and hydrogen peroxide induced significant conformational changes in keratin, particularly affecting disulfide bridges and oxidized sulfur species, which may inform the development of hair restorative treatments.
