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 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 found that oxidative stress, measured through thiol/disulfide balance, is closely linked to the pathogenesis of telogen effluvium.

This study found that novel thiol-reactive cross-linking agents, particularly APA, significantly improved the tensile strength and elasticity of human hair fibers by effectively regenerating disulfide bridges, with potential applications for advanced hair repair treatments in the cosmetic industry.

This study observed that female patients with chronic telogen effluvium had significantly lower levels of total thiol, thiol-disulphide, and disulphide compared to healthy controls, indicating a disruption in oxidative stress balance.

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

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 study found that individuals with acne vulgaris had significantly higher serum total thiol and thiol disulfide levels, as well as a reduced total thiol/thiol disulfide ratio, compared to healthy controls.

In this study, the novel thiol-Michael click perming molecule, MA2-CySS, achieved repeatable perming with reduced oxidative damage, preserving hair keratin's structure while maintaining efficiency comparable to traditional oxidative methods.

This study found that using 1,4-butylenediamine bismaleimide for hair perming through thiol-Michael click chemistry offers comparable efficiency to conventional oxidative methods, with enhanced durability and reduced damage to hair fibres, preserving mechanical, color, and surface properties.

This study found that 1,4-n-butylene dimaleate can restore the mechanical properties of reduced hair by reconnecting disulfide bonds and improving the hair's structural integrity using a thiol-Michael click reaction, compared to untreated reduced hair.

In this study, nanoparticles developed with Minoxidil-loaded thiolated β-CDs showed promise for topical scalp use, as they significantly improved drug retention on hair and displayed no irritation in rabbits.

This study found that nanoparticles developed with minoxidil-loaded thiolated β-cyclodextrins showed improved drug retention on hair surfaces and did not cause skin irritation in rabbits, suggesting potential for topical scalp disease treatment.

Women with telogen effluvium have an imbalance in thiol-disulphide, suggesting oxidative stress may contribute to hair loss.

This study found that thiol disulfide homeostasis is balanced in male patients with androgenetic alopecia, though oxidative stress may be more prominent with emotional stress and vitamin D deficiency.

Topical thiols may prevent hair loss caused by certain chemotherapy drugs.

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 reported that a modified version of Thymosin beta 4, called PEG-rTβ4, demonstrated potential as a treatment for acute myocardial infarction by improving cardiac function and reducing cell death via specific biochemical pathways, suggesting its promise in drug development efforts.

This article discusses the potential role of nutritional ingredients, such as thiols and tannins, in triggering pemphigus, and reports no new empirical findings.

This study found that keratin derivatives with functionalized thiol groups improved binding to both natural and bleached hair fibers, suggesting a promising strategy for enhancing keratin's durability in hair repair.

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 review discusses hair straightening techniques, products, and safety risks, providing guidance for dermatologists to advise patients effectively; it reports no new clinical results.

This review summarizes the potential of N-acetyl-cysteine in managing diseases linked to redox imbalance, discussing its effects from cellular mechanisms to clinical applications, though further research is suggested for broader use.

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 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 chapter reviews the anatomy and structure of hair, discusses hair damage and analyses, and explores methods for processing hair changes, but presents no new research findings.

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.

Some chemicals can permanently or temporarily remove color from skin and hair, which can be distressing and is not well-regulated in cosmetics.

In this study, researchers examined juglone's potential as a restoring agent for hair keratin damaged by permanent or bleaching treatments, finding that juglone formed Michael adducts with cysteine residues, leading to a more regular hair surface as observed via IR spectroscopy and SEM analysis.
