This study found that good quality protein supplements or rumen-protected methionine increased fiber yield in Angora goats and, to a lesser extent, in Cashmere goats.

The researchers reported that disrupting ATRA signaling by deleting RDHE genes in the hair follicle led to altered hair follicle cycles, composition, and gene expression, indicating RDHEs' role in hair follicle signaling coordination.

This article reviews the potential hair-protective effects of Onion and Aloe vera against damage from hair dyes but reports no new experimental results.

This review discusses in vitro methods for evaluating the effects of hair care products on hair fibers, reporting no new results; the authors emphasize the importance of selecting appropriate and accurate equipment for testing.

In this review, researchers examined the molecular diversity and expression patterns of major skin appendage proteins, like keratins and EDC proteins, in tetrapods, highlighting recent findings in reptiles and birds and identifying knowledge gaps for future research.

This review discusses the potential of protein-based cosmetics, including keratin-based particles and fusion proteins, to improve hair properties such as strength and shape, but it reports no new clinical results.

This study concluded that the receptor-like kinase ERULUS, regulated by auxin, is crucial for modulating cell wall composition and pectin dynamics during root hair growth in Arabidopsis.

This study found that finasteride-loaded liposomal formulations achieved significantly higher skin permeation and deposition compared to conventional gels and solutions, suggesting potential for effective topical application.

In an animal model, this study found that PEG hydrogels delivering M2 macrophage-derived exosomes effectively promoted M1 to M2 macrophage transition and enhanced wound healing.

This study reported that recombinant human hair keratins, K37 and K81, showed higher purity and enhanced fibrin clot formation compared to traditional extracts, reducing bleeding time and blood loss in rat injury models.

This study found that excessive heat caused the most significant structural changes in hair from Caucasian and Afro samples, especially when combined with other treatments like bleaching and straightening.

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 review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

This study found distinct differences in protein expression and wound healing pathways between Acomys cahirinus and Mus musculus, highlighting potential targets for reducing fibrotic response in mammals.

This study suggests that behavior modification, semistarvation ketogenic regimens, and surgical therapy could be experimental approaches for different degrees of obesity, with their efficacy varying by the degree of weight excess.

This review discusses the effects of dietary protein and its components on cholesterol, essential fatty acids, and possible health consequences, but presents no new clinical findings.

This review discusses the therapeutic potential and challenges of using extracellular vesicles derived from mesenchymal stem cells, concluding that they may have a comparable therapeutic potential to the original cells despite current challenges in their application and production.

In this study, supplementing low-protein diets with 0.75% methionine maintained growth performance, improved fur quality, enhanced nutrient utilization, and supported intestinal microbiota balance in blue foxes, with significant results on several biochemical parameters and nutrient digestibility observed.

This study found that human meibomian glands differ significantly from free and hair-associated sebaceous glands in morphology and lipid composition, making them highly specialized holocrine glands.

This source reviews the application of various natural substances, particularly plant extracts from the Ayurvedic system, in promoting hair growth, addressing common issues like pigmentation, dandruff, and hair loss.

This study found that hair membrane fluidity is low in the cuticle but high in the cortex and medulla, with treatments like ionic surfactants and oleic acid increasing fluidity in hydrated hair; however, dehydration significantly reduces fluidity throughout the hair.

This study found that a high-fat diet in macaques led to severe gastrointestinal inflammation and chronic wasting, with more pronounced effects in females, highlighting the potential risks of certain dietary interventions in obesity models.

In this study, researchers observed that including raw cotton seeds in the diet of rats led to hair loss, suggesting gossypol in the seeds may be responsible.

This study found that a hair conditioner using peptides from Pneumatophorus japonicus heads improved damaged hair's structure, gloss, and smoothness more effectively than a commercial wheat protein conditioner by increasing amino acid content and interacting with hair keratin.

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 study identified that a deficiency in the palmitoyl transferase enzyme, due to a mutation in the Zdhhc13 gene, led to severe physiological abnormalities in mice, including skin, bone, and systemic amyloid issues.

This study found that thermal hair-straightening devices significantly damaged the cuticle and cortex of virgin Asian and Caucasian hair, with Asian hair experiencing more protein loss than Caucasian hair.

This review compiles EV proteomics data and reports that while MSC-derived EVs show promise in skin therapeutics, variability in protein cargo highlights the need for standardized methodologies in understanding process impacts.
