In this study, researchers identified a highly reactive, isozyme-specific sequence for TGase 3, contributing to understanding its distinct functional role and activity distribution in the mouse epidermis.

This research provides insights into how keratin hydrogels, modified to control disulfide crosslinking, may function as a treatment platform for bone injuries.

This study found that AP collagen peptides can promote hair growth by supporting the health of hair follicle cells, as they stimulate cell proliferation, counteract apoptosis, and enhance antioxidant enzyme expression, suggesting potential as a treatment for hair loss.

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.

In this study, adults with mild-to-moderate hair damage taking GPVGPS Collagen® daily for 24 weeks showed significant improvements in hair luster, strength, thickness, and density compared to placebo, with no safety concerns reported.

This study discusses the effects of incorporating various amino acids in hair care products, noting improvements in hair surface properties and color retention when integrated with conditioners.

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, Korean adults with damaged hair who took 3g/day of low-molecular-weight collagen peptide GT for 24 weeks showed significant improvements in hair gloss, elasticity, and scalp elasticity compared to placebo, without any adverse events.

A new mutation, Glu402Lys, in hair keratin is linked to variable symptoms of monilethrix.

This study found a novel nonsynonymous genetic variant in the hHb1 gene of a family with monilethrix, which differs from ten previously reported pathogenic mutations.

This review discusses various environmental and chemical factors that contribute to hair shaft disorders, such as fractures, and highlights the potential roles of cysteine and glutamine in hair health, but reports no new results.

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 case study describes a six-month-old boy diagnosed with Netherton syndrome, featuring ichthyosiform erythroderma and alopecia, possibly linked to aminoaciduria.

In this case report, researchers described a female child with total alopecia due to a mutation in the SNRPE gene, emphasizing the need for updated genetic testing as knowledge advances to avoid diagnostic delays in hereditary nonsyndromic hypotrichosis.

This study identified a novel splice site mutation in the LIPH gene associated with autosomal recessive woolly hair, contributing to understanding the genetic basis of this condition.

The researchers reported that the novel MBTPS2 variant p.Glu172Asp found in a male proband is likely pathogenic, consistent with osteogenesis imperfecta symptoms and molecular signatures, including disrupted fatty acid metabolism and collagen production.

This review analyzed how the chirality of peptide building blocks affects their self-assembly into hydrogels, comparing structural and mechanical properties of homochiral and heterochiral peptides, and discussed potential biological applications of these peptide systems.

This study reports that compound heterozygous loss-of-function mutations in the HEPHL1 gene in a child were associated with abnormal hair and cognitive issues, linking altered ferroxidase activity to hair disorders.

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 genetic mutations associated with Hutchinson-Gilford progeria syndrome and reports no clinical results; the authors emphasize the importance of cardiovascular monitoring in management.

This study identified a novel insertion mutation in the hairless gene that may contribute to the development of congenital atrichia with papular lesions in a Pakistani family.

This study found that collagen remodeling is more active in anagen-stage skin than in telogen-stage skin in mice, suggesting that collagen modifications may support hair follicle growth and migration.

In this study, researchers identified a collagen fragment, sample-1707, expressed in E. coli, which forms nanofibers and promotes blood clotting, osteoblast differentiation, and skin cell regeneration, making it a promising biomaterial for skin care, with a large-scale production yield of 600 mg/L.

This study reported that hydrogels created from keratins extracted from human hair exhibit antibacterial properties and enhance tissue regeneration, suggesting their potential use in full-thickness skin repair, as demonstrated by increased collagen production and improved healing in vivo.

Metabolic disorders can cause hair structure defects and growth issues, but amino acid levels in hair remain normal.

This study found that genetically variant peptides from human hair can reliably identify individuals despite differences in age and storage conditions, provided environmental and processing factors are controlled.

This study found that a newly developed keratin active ingredient effectively prevents aging damage in hair by strengthening its structure after exposure to simulated environmental stress.
