This study found that bleached hair showed optimal protein structural integrity and tensile strength at pH 5, with significant changes in cross-linking, water content, and diameter at more alkaline or acidic levels.

This review summarizes the roles of matricellular proteins in skin stem cell niches, highlighting their contribution to stem cell fate, self-renewal, and potential implications for wound healing and aging.

This study concludes that SPARC is likely a secondary response during the hair cycle's transitional phases, indicating tissue-remodeling processes similar to those in wound repair, rather than initiating these transitions.

Scientists made nanoparticles from human hair proteins to improve drug delivery.

This study found that using a microfiber towel to dry human hair better preserves hair keratin integrity and wear resistance compared to blow-drying or using a cotton towel, as indicated by stronger alpha-helix structure in FTIR analysis.

This article discusses themes in the molecular structure of hair and reports no new research findings.

This study investigated the formation of a specific chemical crosslink in hair proteins and explored the role of transamidase enzymes in hair follicles.

In this study, experimentally induced weight loss in merino sheep led to a decrease in wool fiber diameter and increased expression of certain high sulfur and glycine-tyrosine proteins, potentially impacting wool quality and industry preferences.

This paper reviews strategies for modifying the structure and protein delivery of electrospun nanofibrous materials, emphasizing their potential to guide tissue repair and highlighting current challenges and future research directions in this emerging field.

This review discusses the effects of protein-based cosmetics on hair properties and reports no new research findings, suggesting potential benefits for developing advanced, sustainable hair products.

In this study, researchers found that the naked (N) gene in mice indirectly affects the synthesis of structural proteins in mouse hair, resulting in reduced high tyrosine protein content and unusual amino acid compositions.

This review summarizes techniques like Raman spectroscopy, nanoindentation, and small-angle X-ray scattering to explore the biophysical interactions in collagen fibers, aiming to enhance understanding of fibroblast behavior and mechanisms involved in organ fibrosis and healing processes.

This article reviews methods for dissolving hair proteins and describes how solvents and molecules with hydrophobic groups interact with hair; it presents no new research findings.

In this study, treatment with aqueous KCN selectively converted disulfide bonds to monosulfide crosslinks in hair, leading to changes in microstructural properties and rubberlike elasticity under specific laboratory conditions.

This study found that blocking autophagy in Atg7-deficient mouse hair keratinocytes altered the molecular composition of hair shafts by increasing the abundance of proteins involved in protein turnover while keratins remained unchanged, highlighting autophagy's role in reducing non-cytoskeletal protein concentrations in hair.

This study investigated the effect of peracetic acid treatment on hair fiber structure and found that disulfide bond oxidation altered thermal properties while preserving the α-crystal structure, suggesting different stabilizing interactions in hair fibers.

In this study, the authors concluded that a hydrolyzed eggwhite protein treatment promoted the reconnection of disulfide bonds in excessively bleached hair, after reduction and oxidation processes in permanent waving.

This paper reviews the evolution of skin appendages and keratin-associated proteins among amniotes, proposing a model for their genetic divergence without new experimental results.

In this study, researchers found that size polymorphisms in certain hKAP1 genes are linked to the hKAP1.1B and hKAP1.3 genes, arising from intragenic deletions and duplications in Japanese and Caucasian populations.

This study identified numerous size polymorphisms in the human ultrahigh sulfur KAP4 genes due to intragenic sequence variations, suggesting these polymorphisms may have arisen through deletions and duplications during evolution.

This study found that inhibiting AP1 transcription factor activity in the suprabasal epidermis of mice alters keratinocyte gene expression, reducing barrier integrity and mimicking human keratoderma.

This study found that genes in the human keratin-associated protein 1 family may have evolved mainly through gene duplication of cysteine-repeat motifs.
