This research studied European human hair, finding that cysteic acid and protein carbonylation increased with both chemical and photochemical oxidation. Protein carbonylation was highlighted as a more sensitive marker for photochemical oxidation, providing better in situ visualization of hair damage than cysteic acid.

This study found that certain tandem repeats predict darker hair color across diverse ancestry groups and can contribute to a polygenic score for hair color, independent of SNP variation.

In this review paper, the authors explored the composition and role of lipids in human hair, highlighting their importance for hair texture, moisture retention, and tensile strength, while noting that the understanding of hair lipids' functions remains controversial and requires further research.

This review covers the history, symptoms, and treatment progress for Hutchinson-Gilford Progeria Syndrome, noting that while no cure exists, understanding its molecular mechanism may improve future treatment strategies.

This review discusses the role of nutrients in hair graying management and finds a possible link between low copper, iron, and vitamin B12 levels and premature hair graying.

Eating a balanced diet with specific nutrients can help manage menopause symptoms and prevent related health issues.

This review covers skin manifestations in chronic kidney disease, highlighting their impact on quality of life, associated prognostic indicators, and available treatments, but provides no new clinical results.

This study found that washing hair after reduction in a permanent waving process allows for significant reformation of disulfide cross-links, enhancing the strength and elasticity of hair fibers.

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

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 explores how recombinant protein hydrogels, employing molecular engineering and crosslinking strategies, offer advanced applications in regenerative medicine by mimicking extracellular matrix dynamics and providing enhanced mechanical, environmental, and biological properties.

This research found that keratin hydrogels derived from human hair may support cell viability and proliferation, indicating potential as 2D and 3D soft tissue culture scaffolds.

Hair straightening methods have advanced to improve effectiveness and reduce damage, but still rely on heat and chemicals.

The method effectively analyzes human hair proteins, especially nonfilamentous ones.

This study demonstrated effective delivery of CRISPR/Cas9 components to dermal papilla cells in androgenic alopecia animals using ultrasound-activated nanoparticles, resulting in specific gene editing and hair growth recovery.

This study concluded that bleach treatment partly transforms the hydrophobic top layer of human hair cuticles into a hydrophilic surface with clustered cysteic acid, visualized at the nano-scale using dynamic Chemical Force Microscopy.

This study examined the structural and biochemical mechanisms of human lipocalin prostaglandin D synthase, detailing substrate and product binding processes at the catalytic site and suggesting potential for drug delivery targeting hydrophobic molecules.

This review discusses the role of keratin-associated proteins in the growth and characteristics of wool and hair fibres from sheep and goats, and highlights areas for future research, but it presents no new findings.

This study suggests that extracting hair proteins at relatively high temperatures may enhance their hemostatic properties by altering their secondary structure and increasing the precipitation of soluble fibrinogen.

This study proposed a network model for the cross-linked structure of keratin-associated proteins in hair and wool fibers, suggesting notable differences between the two, potentially affecting hair fiber elasticity.

This study found that adding dithiodiglycolic acid to the hair straightening process decreased chemical damage and preserved the structural integrity of the hair matrix compared to using thioglycolic acid alone.

This study evaluated quercetin's potential as a treatment for cats with Feline Atopic Skin Syndrome, finding it significantly reduced clinical scores in certain symptom groups like Head-and-Neck Pruritus and Miliary Dermatitis, although improvements in oxidative stress markers were not clearly significant.

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 demonstrated that human hair keratins have strong antioxidative properties, providing protection against oxidative stress in human dermal fibroblasts, suggesting their potential as antioxidizing supplements.

This review discusses the biology and development of skin melanocytes, but reports no new clinical findings.

This study found that ultrasonication pre-treatment at various power levels improved the color, protein solubility, and degree of hydrolysis of fish protein hydrolysates from mackerel side streams, and potentially reduced bitterness by decreasing hydrophobic free amino acids.

This review discusses advances in understanding hair and hair follicle structure, gene expression, and molecular signals in hair formation, without reporting new clinical findings.

This study found that in mice lacking EGFR, elevated Wnt signaling disrupts hair follicle development by affecting cell proliferation and differentiation, revealing a critical role for EGFR in regulating these processes.

This study provided the first proteome dataset for alopecia areata, revealing novel pathways in the disease mechanisms that may lead to new therapeutic targets.
