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 review examines the design and evaluation parameters of depilatory formulations but reports no new empirical findings.

This study found that FGF18 is crucial for regulating hair follicle rest and growth phases, as its absence in mice leads to a shorter resting phase and rapid hair cycling.

This study suggests that melatonin may enhance wool growth in cashmere goats by activating sulfur metabolism genes and high-sulfur protein genes, which are crucial for providing sulfur-containing amino acids needed for wool quality.

This study explored gene expression in Changthangi goats and found that higher expression of keratin-related genes and specific signaling pathways may play a role in the development of Pashmina fiber.

This study demonstrates that polarized second harmonic generation imaging effectively monitors wool fiber stretching, revealing significant structural changes in keratin alignment that improve textile performance.

This study observed that canine follicular tumors are an uncommon type of skin neoplasia in Croatian dogs, often benign but with a small percentage presenting malignancy, and vary based on the breed's hair growth type.

This article proposes an updated naming system for keratin-associated proteins and genes, aiming to improve data storage and retrieval by including species information and genetic variation.

This study found that small proline-rich proteins modify the biomechanical properties of cornified cell envelopes in rodent forestomachs, potentially affecting the tissue's ability to withstand mechanical stress.

This review explores various topics related to skin diseases, hormones, receptors, growth factors, and therapeutic approaches, but it provides no new research findings.

This case study described the diagnosis of a trichofolliculoma in a 56-year-old woman, emphasizing its dermoscopic features and histological aspects that confirmed the tumor type, with no recurrence observed after excision.

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.

This study found that pilomatricomas exhibit co-expression of hair keratin hHa5 and HOXC13 in lower transitional cells, but lack LEF1 and β-catenin co-expression necessary for canonical Wnt signaling pathway-controlled cortical differentiation.

This study developed a biobased copolymer called SELP::KP, showing improved hair strength, elasticity, and conditioning properties while being a safer alternative to conventional chemical treatments, based on application to human hair in a laboratory setting.

This review summarizes the cell type distribution and functional significance of human keratins, emphasizing their roles in tumor diagnosis and potential clinical applications, and reports no new clinical findings.

This review discusses recent advancements in understanding neuroendocrine regulation of keratin biology and highlights the potential of neurohormones to treat skin disorders, but it reports no new clinical results.

This study used proteomics to identify various proteins in human hair, which may help develop novel biomarkers for hair health, disease, and aging.

This study used proteomic techniques to analyze human hair proteins, revealing keratin heterogeneity and identifying posttranslational modifications, such as cysteine trioxidation and methylation.

The researchers found that HOXC13 regulates different keratin proteins in a mixed manner, with certain SNPs impeding this regulation, while also demonstrating negative-feedback by HOXC13 and positive regulation by LEF1 and melatonin on the HOXC13 promoter.

This review evaluates existing research on Keratin 15 to assess its validity as a marker for epidermal stem cells, reporting no new results.

This study observed that hepatocyte adhesion to human hair keratin biomaterials was mediated by the hepatic ASGPR, as blocking this receptor reduced cell attachment.

This study suggests that the keratins found in reptile and bird skin appendages evolved independently from mammalian hair keratins, highlighting convergent evolution in these species.

This study found that polymorphisms in the KAP8.2 gene in Chinese Inner Mongolia cashmere goats are associated with variations in cashmere fibre diameter, suggesting its potential as a molecular marker for this trait.

In this study, oral collagen peptides increased certain gene expressions related to epidermis development and the hair cycle in hairless mice skin, suggesting potential links to hair health.

In this study, a keratin hydrogel improved survival rates and functional recovery in rats with spinal cord injuries, suggesting potential for SCI treatment that merits further investigation.

This article reviews the role of keratins in epithelial function and structure, discussing their involvement in growth control, organelle functions, and pathomechanisms of disorders, but reports no new clinical results.

This study demonstrated that urea significantly accelerates the diffusion of poly(ethylene imine) into bleached human hair by increasing the diffusion coefficient twofold.

This study identified a novel mutation, R430Q in the KRT86 gene, in a Han family with monilethrix, which may contribute to the disease's pathogenic mechanism.

This study found that keratin-associated proteins related to metallothionein and occludin appear in various animals, suggesting they may have roles beyond hair characteristics and were later adapted for hair production.

This study demonstrated that a daily oral supplement of 1000 mg Kera-Diet® improved hair and nail conditions in women experiencing acute telogen effluvium and brittle nail syndrome over three months.
