This study observed that hair follicle cuticular cells undergoing keratinization were significantly thicker than those in a normal hair shaft, due to incomplete loss of cytosol.

This study observed abnormal extracellular matrix patterns in hair follicles from alopecia areata patients, particularly in the dermal papilla of large anagen follicles and in catagen follicles from lesional sites.

In this first reported case, a 42-year-old female with Parry Romberg Syndrome was treated using hyaluronic acid filler, which the authors suggest may serve as a safe, simple, and cost-effective alternative to more complex surgical methods.

This study observed that rat dermal tissue cultures, rich in hair follicle cells, produce various glycosaminoglycans, including hyaluronic acid and dermatan sulfate, which change in synthesis and sulfation patterns over time.

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 case study reports that a 45-year-old woman developed a painless nodule in the lower lip four weeks after receiving hyaluronic acid filler, which required surgical removal, highlighting the potential for delayed complications from lip augmentation procedures.

This article describes the structure and components of hair cuticle cells and their intercellular junctions but reports no new clinical results.

In this study, researchers used 3D printing combined with cryogenic crosslinking to develop gelatin/oxidized alginate scaffolds and found that adding 5% hydroxyapatite improved mechanical properties and osteogenic effects, enhancing bone tissue regeneration, though 10% hydroxyapatite offered no additional osteogenic benefits and reduced shape fidelity.

This study developed keratin-based hydrogels with improved water solubility and tunable properties, demonstrating excellent cytocompatibility, suggesting potential for biomedical applications.

This research found that immobilizing type I atelocollagen onto artificial hair significantly improved the adhesion and long-term fixation of the hairs in the human scalp, indicating high biosafety and enhanced tissue integration.

This study found that eccrine duct dilation is significantly more frequent in cicatricial alopecias compared to noncicatricial alopecias, possibly due to the scarring process.

This case report describes a proliferating trichilemmal cyst that underwent malignant transformation, with specific keratins identified in the tumor but no epidermal keratin detected.

In this double-blind study, a novel hyaluronic acid gel for lip augmentation was found to be as effective and safe as a commercially available gel, with similar adverse event profiles and high patient and investigator improvement ratings over six months.

This study found that electronically-operated pneumatic injections for administering a peptide-hyaluronic acid combination were well tolerated and led to significant improvement in hair density and thickness for men with androgenic alopecia over six months, though the exact mechanism remains uncertain.

This study characterized keratin-based biomaterials that self-assemble into hydrogels, demonstrating their potential to achieve hemostasis in a lethal liver injury model through specific biomaterial-receptor interactions.

This case report describes an 18-year-old man with pili annulati, characterized by a "shagreened" appearance of the hair shaft with alternate bright and dark bands and wide holes throughout the cortex.

This article discusses how activating the hexosamine pathway may enhance skin homeostasis by increasing hyaluronic acid secretion and supporting hair follicle stem cell self-renewal, but reports no new results.

This study highlights the significant risk of vascular embolism associated with hyaluronic acid filler injections, emphasizing concerns about potential irreversible damage when fillers are injected in "unexplored" facial areas due to complex and variable facial anatomy.

This study found that GelMA/HAMA bioink shows promise for 3D printing skin equivalents, as it effectively mimics the native skin's properties and supports hair follicle structure development.

This study observed that hyaluronan's transformation into HA·3Ca and its hydrate increases drug absorption by changing its molecular characteristics, influenced by zwitterionic character and acidic pH.

This study used rapid-freezing immunocytochemistry to successfully map the ultrastructural localization of hair keratins in human scalp hair, primarily finding them in macrofibrils in the cortex and endocuticle.

In this study, trypsin digestion was found to be a faster and more efficient method than the explant technique for extracting bulge-derived keratinocytes from adult scalp biopsies.

This study reviewed cases of filler-induced alopecia and found that hyaluronic acid injections were most commonly associated with this condition, highlighting that hyaluronidase treatments can rapidly restore hair density, while alternative interventions need further exploration.

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 study found that scanning electron microscopy revealed considerable abnormalities in hair morphology in MPS I, II, IIIA, and IIIB patients, potentially related to heparan sulfate accumulation.

This journal overview highlights the expansive coverage of cosmetic and reconstructive skin surgery, but reports no new research findings.

This study found that the Meibomian gland shares structural and cytokeratin composition similarities with hair follicles, and plays a role in hyper-keratinisation observed in obstructive Meibomian gland dysfunction.

This study reports that the white rhinoceros has a unique integumentary structure among large herbivores, characterized by thick epidermis, organized collagen bundles, and the presence of coiled sweat glands.
