This study found no statistical difference in thiol-disulfide balance between telogen effluvium patients and controls, suggesting oxidative stress may not affect telogen effluvium through this mechanism.

This study observed that mercury-lamp irradiation may cause cleavage of disulfide bonds in keratins of white hair, leading to the formation of thiols in laboratory settings.

This study explored using tyrosine as a cross-linking agent for curling Asian hair and found that it could shape hair effectively before washing without damaging the fibers, though the method was less effective after washing compared to commercial products.

This study found that long-term smoking was associated with increased mitochondrial DNA deletions in hair follicles, especially among smokers with low plasma glutathione S-transferase activity.

This study found that using a bicomponent reduction system with TGA and DTDG for hair straightening limited hair damage by forming only thiol groups, while a TGA-only system formed more damaging mixed disulfide groups.

This chapter reviews hair anatomy, hair shaft structure, and various cosmetic treatments that can alter or damage hair, but it presents no new research findings.

This study reports that hair damage from bleaching is associated with the oxidative cleavage of fatty acid thioester bonds, detectable by measuring the decrease in mass spectrometry peak at m / z 76.

This study suggests that the outermost hair cuticle surface is rich in 18-methyleicosanic acid (18-MEA), supporting previous findings of its multilayer lipid and protein structure.

This study observed that repeated perm treatments decrease disulfide bonds in hair due to their conversion largely into cysteic acid, affecting the waving efficiency depending on the reduction agent used.

In this study, researchers evaluated the binding of keratin-associated proteins and α-keratins to human hair fibers, finding that chemical preactivation significantly enhanced binding to natural hair, while perming altered binding characteristics and increased penetration depth.

This study suggests that human hair keratin-based gradient hydrogels incorporating silver ions may serve as promising dermal templates for wound healing, demonstrating favorable mechanical properties, cell interaction, and antibacterial activity.

This study found that a silver ion cross-linked thiolated protein hydrogel, O3G7, significantly enhanced acute wound healing in mice by increasing collagen content, neovascularization, and reducing inflammation markers compared to a control group.

This study found that alkylation of kerateine cysteine residues created a cell-compatible method for controlling hydrogel erosion rates and therapeutic agent release in keratin-based systems.

This study found that, despite the unchanged total level of 18-MEA, deletion of the Sox21 gene disrupts its attachment to the hair cuticle, increases cholesterol sulphate levels, and differentially affects ceramide composition.

This thesis developed stimuli-responsive nanocarriers, demonstrating their potential for targeted genetic material delivery with reduced toxicity and diagnostic applications, and explored pH-sensitive nanogels for effective skin drug delivery and monitoring.

In a study on diabetic mice, researchers developed a protein-based hydrogel that leverages zinc ions and the natural compound phellopterin to promote cutaneous nerve regeneration, angiogenesis, and tissue remodeling in diabetic wounds, highlighting its potential for advanced wound therapy.

This study found that a peptide treatment using Protein disulphide isomerase improved the mechanical and thermal properties of over-bleached hair by promoting deeper peptide penetration and attachment.

This study investigated various proteins as eco-friendly hair perming agents for Asian hair and found that bovine serum albumin and keratin achieved perming results comparable to commercial products, while also increasing hair moisture, indicating a protective effect during heat styling.

In this study, sodium thiosulfate was observed to promote hair growth in mice by encouraging hair follicles to enter the growth phase and complementing the effects of minoxidil, suggesting potential benefits for hair loss treatment.

This review focuses on the roles of amino acids, peptides, and proteins in cosmetics, highlighting their importance in skin health and their potential for development in personal care products due to their unique properties and biocompatibility.

In this study, the researchers observed that biotin administration in biotin-deficient children with alopecia eliminated certain membrane proteins from their blood, suggesting that biotin might regulate these proteins' expression.

In this study, researchers found that a protein-enriched cream made from Spirulina platensis improved the physical structure of natural hair, as evidenced by more intact and smoother cuticles compared to a control cream without protein, suggesting its potential for hair care applications.

This study found that AtT-20 pituitary cells with higher cAMP-dependent kinase activity had larger calcium currents and significantly increased beta-endorphin release compared to cells with lower kinase activity.

This study found that PEGylation of nanoparticles enhances their penetration into hair follicles, with higher molecular weight PEG resulting in deeper follicular delivery.

This study used molecular dynamics simulations to illustrate the complex molecular behavior of the hair surface F-layer, highlighting how fatty acids interact with 18-MEA under different conditions.

This study found that protein extracts from human hair demonstrated significant antioxidant abilities, protecting human dermal fibroblasts from oxidative stress, suggesting potential for biomedical applications.

This chapter reviews surface plasmon resonance (SPR) methodology and its applications in basic science and human disease without reporting new clinical results.

This study found that androgen binding in male rat livers involves specific androgen receptors, which decrease with castration and are inducible in female livers with testosterone.

This review discusses the role of acyl-CoA binding protein (ACBP) in the epidermal barrier, noting that its disruption in mice is linked to skin and fur abnormalities; it reports no new clinical results.

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.
