A fatty acid/protein complex in human hair helps protect it from damage.

This study found that papain/bisulfite disintegrates human hair cuticles by dissolving the endocuticle, potentially accelerated by ethanol's removal of cell membrane material.

This study found that keratin films made from human hair can potentially substitute for human nail plates in drug permeability studies, but they show higher sensitivity to penetration enhancers compared to bovine hooves.

In this clinical study, a vegan collagen builder (VEGCOL™️) was shown to safely and effectively improve hair growth, skin smoothness, wrinkle reduction, and joint pain relief in adults, with enhancements varying by dose over a 60-day period.

This study optimized the extraction process of bear grease through enzymatic hydrolysis and found that it was rich in unsaturated fatty acids, enhancing its hair growth-promoting properties in mice compared to traditional methods.

This review discusses the isolation, characterization, and potential clinical applications of tissue-derived extracellular vesicles in cancer diagnosis, prognosis, and treatment, noting their significance but highlighting the risks and need for appropriate protocols.

This study found that cystatin M/E strongly inhibits human cathepsin V and cathepsin L via distinct non-overlapping sites, suggesting an important role in human epidermal differentiation and hair follicle morphogenesis.

This study describes a case where a patient with Vitamin B12 deficiency symptoms achieved increased serum B12 levels and symptom relief through treatment with Amyron syrup and Amlycure DS capsules, rather than traditional B12 supplements.

This pilot study found that using a topical Carica papaya latex gel for 28 days reduced hair fall and promoted hair regrowth in individuals with Indralupta, although the bald patch size did not significantly change, indicating the potential need for longer treatment or additional interventions.

This study demonstrated that cryogelation of human hair keratin allows the development of 3D scaffolds with tunable properties, supporting cell adhesion and proliferation for potential biomedical applications.

This study found that PCL-based nanofiber scaffolds enhanced cell proliferation and extracellular matrix deposition, suggesting they show promise as a cell delivery system for improving skin wound healing.

This study found that engineered skin substitutes made with skin-derived precursors and epidermal stem cells can regenerate hair follicles after grafting into nude mice.

This review discusses the role of Nutrease powder in managing hormonal disturbances in polycystic ovary syndrome and reports no new clinical results.

This study found that cardiac fibroblasts significantly enhance the maturation of neonatal mouse and human embryonic stem cell-derived cardiomyocytes, suggesting a pivotal role in postnatal heart development and disease.

This chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.

This article discusses how drug molecules integrate into hair fibers, focusing on biological transport mechanisms and physicochemical factors, but reports no new experimental findings.

This study synthesized existing research on 11 tropical seed varieties, underscoring their potential in food, pharmaceutical, and agricultural industries due to their phytochemicals and nutrients, such as phenolics and vitamins, which could reduce waste and support sustainable practices.

This study utilized a mouse model of traumatic brain injury to reveal that acute neurotrauma triggers widespread lipid metabolism reprogramming and storage lipid accumulation in microglial and monocyte populations, leading to lysosomal dysfunction, inhibited autophagy, and exacerbated inflammation through a pathological feedback loop.

This research reviews the scientific literature on bone broth extract, exploring its nutritional composition, potential health benefits, food industry applications, and risks such as heavy metal and antibiotic contamination. Results are not reported in this summary.

This discussion concluded that many herbal home remedies are effective for treating alopecia and other hair conditions without causing adverse reactions, as opposed to allopathic medicines that often have undesirable side effects.

This study explored the structure and function of lipocalin prostaglandin D synthase, revealing its dual role in substrate catalysis and as a lipophilic ligand carrier, potentially informing future drug delivery design.

This study found that individuals with alopecia areata had significantly higher serum levels of retinol-binding protein 4 and increased IgG immunoreactivity against it, suggesting a role in the disease's pathogenesis.

In this study, the researchers found that deleting ceramide synthase 4 in the skin's epidermis alters stem cell differentiation, disrupting hair follicle structure and barrier function, potentially leading to immune responses similar to atopic dermatitis.

This review examines the evolving field of nanozymes, highlighting their unique properties and biocatalytic capabilities that challenge traditional concepts of biocatalysis, with implications for sustainable applications and potential roles in physiological processes and disease pathogenesis.

This review highlights how advanced nanocarrier and microneedle-based transdermal drug delivery strategies can potentially improve the treatment of skin diseases by enhancing site-specific drug delivery, increasing skin penetration, and reducing systemic toxicity compared to conventional methods.

This research examined the ultrastructure of deer hair fibers and found significant variations in diameter, cuticle thickness, and intermediate filament arrangements among different fiber types.

This review discusses the potential therapeutic role of the edible plant Solanum nigrum for managing COVID-19 symptoms and post-COVID complications based on in silico docking and pharmacological studies, but reports no new clinical results.

This review explores herbal medications for skin disorders, covering their clinical efficacy, safety, and common drug interactions, but reports no new clinical results.

This article reviews the structure, genomic organization, and pathogenesis of SARS-CoV-2 and discusses current efforts in prevention and treatments for COVID-19 without reporting new clinical results.

In this study, researchers formulated a pomade using papaya seed oil and virgin coconut oil at various concentrations and found it to be stable, non-irritating, and preferred by users, with the 7.5% concentration being most favored for providing shiny and moisturized hair.
