This study found that a newly produced version of KGF-1 with 135 residues maintained biological activity and could serve as an alternative to the standard 140-residue KGF-1.

This study found that CTHRC1 is crucial for sweat gland function and vascular network integrity in mice, and its administration improved sweat gland performance by reconstructing nearby blood vessels.

This study suggests that trichohyalin is modified by peptidyl-arginine deiminase before being cross-linked by TGase 3, allowing the formation of rigid structures in hair follicle cells.

This research reports that copper-quercetin complexes show strong potential in antioxidation and cancer therapy, while their effects on specific cell death pathways warrant further investigation.

This study suggests that the mechanical robustness of hair may be enhanced by the binding interactions of keratin-associated proteins, particularly KAP8.1, with intermediate filament proteins.

This research found that the transfer reaction catalyzed by human plasma and guinea pig hair follicle transglutaminases aligns with a ping-pong mechanism involving peptide-bound glutamine.

This study demonstrates that the amino-terminally shortened KGF-1 variant with 135 residues maintains biological activity, suggesting it may serve as an alternative to the original KGF-1 for certain therapeutic applications.

In a mouse model of androgenetic alopecia, this study developed a treatment combining a copper-curcumin nanoparticle oleogel with traditional Gua Sha therapy, which augmented hair regeneration more effectively than minoxidil by improving the follicular microenvironment and regulation of inflammatory responses.

This study identified trichohyalin as an early differentiation marker in hair follicles, with potential structural roles related to alpha-helical formations, based on the partial characterization of its cDNA in sheep.

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.

This study suggests that low molecular weight fish collagen peptide may promote hair follicle growth and regeneration, improving overall hair quality in mouse models.

This study identified two key pentapeptide quasi-repeats in human keratin-associated proteins, which are similar to motifs found in sheep wool.

A peptide in shampoo can promote hair growth and improve hair condition.

This study identified a human sequence likely coding for a new ultra-high sulphur protein, which may aid in understanding hair differentiation and the molecular basis of human trichothiodystrophy.

This study suggests that APC collagen peptides may accelerate hair growth and promote overall hair health by enhancing cellular proliferation and activating specific signaling pathways in human and mouse models.

This study suggests that reversible hypopigmentation in homocystinuric patients may result from tyrosinase inhibition by homocyst(e)ine, with in-vitro experiments showing copper sulfate reversing this inhibition.

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 study presents evidence that specific thymus-derived peptides affect human hair follicle growth, identifying thymulin as a potential hair growth stimulator despite interindividual response variations.

This study identified molecular elements controlling the expression and stabilization of THH protein in hair follicle cells, revealing key mechanisms that support hair shaft development in mice.

This study found that children with pituitary dwarfism had higher zinc and copper hair concentrations and lower manganese concentrations compared to healthy children.

This study found that orally administered hydrolyzed keratin peptide promoted hair growth and enhanced cellular proliferation and antioxidant capacity in mice and human cell models, suggesting its potential as a functional food ingredient for hair health.

This study found that homocysteine-keratin accumulation in human hair increases towards the tips, linked to copper/iron-catalyzed demethylation of methionine, and may contribute to keratin damage.

This study demonstrated that dietary cupric citrate improved growth performance and nutrient utilization in broilers, while also altering their intestinal microbiota and increasing the pH in the duodenum and jejunum.

This study identified that copper depletion in dermal papilla cells reduced hair growth by boosting ROS levels, but ROS scavengers like NAC and ascorbic acid partially alleviated this effect.

This study suggests that hepatocyte growth factor (HGF) may play a role in hair follicle neogenesis and that an HGF mimetic could enhance skin substitute development.

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 Gp₄G increased hair length, papilla cell numbers, and versican deposition in treated animals, potentially through alterations in hair follicle phases and nucleotide concentrations.

TAT-GILZ peptide promotes hair growth by boosting stem cell activity.

In a murine model of androgenetic alopecia, this study found that the newly designed IGF-1 biomimetic peptide Ac-GFFY-IGF led to faster and superior hair regrowth compared to minoxidil, suggesting potential for improved human therapies.

In this study, researchers investigated the impact of a bioactive peptide derived from amphibians on hair follicle regeneration in diabetic skin, focusing on its potential to enhance wound healing and reduce infection risk.
