This study found that astilbin downregulates effector CD4+ T cell activities through the CYP1B1/ROS/PPARγ pathway, suggesting its potential use in treating inflammation.

This study investigated the mechanical response of the human hair cuticle to strain and found that cuticular deformation directly corresponded with fiber elongation, revealing significant molecular-level changes in disulfide crosslinks but maintained structural stability, highlighting the role of the cuticle in stress resistance.

In this open-label study, the researchers observed that using Kerascalp hair serum daily for 90 days improved hair thickness, density, and strength while reducing hair loss in subjects with mild to moderate androgenetic alopecia, with benefits persisting even after discontinuation.

CaBP1 and 2 are necessary for maintaining calcium currents and hearing in inner ear cells.

CaBP1 and CaBP2 are important for maintaining hearing by supporting continuous calcium currents and nerve signaling in the ear.

This review discusses the role of platelet-rich plasma therapy in various cosmetic procedures, finding potential benefits in improving tissue homeostasis if harvesting standards are maintained, but reports no new clinical results.

This study found that integrating graphene oxide into a biodegradable composite made from discarded hair keratin enhanced its structural properties, biodegradability, and gas barrier performance, indicating potential use as an eco-friendly packaging material.

This study found that treating damaged hair with maleic-modified amino silicone oil created a highly hydrophobic surface, reducing water content and improving hair's mechanical properties and thermal stability.

This study found that platelet-rich plasma injections led to improvements in hair counts, thickness, and strength in patients with androgenic alopecia, showing promise as an effective treatment with no major adverse effects.

This study suggests that TGase 3 may contribute to hair fiber scaffolding by forming specific isopeptide bonds between keratin intermediate filaments and keratin-associated proteins.

This study found that PCL-Col/ZnO fibrous scaffolds enhanced wound healing and exhibited antibacterial properties, making them promising for use as a wound dressing.

In this study, researchers reported that the application of refolded human K31 keratin protein significantly improved diameter, mechanical strength, and smoothness of chemically damaged hair after a single treatment.

In this study, NuMA's microtubule-binding domain was found to be crucial for correct spindle orientation and skin differentiation, with its loss leading to neonatal lethality in mice.

This study found that while clinical evidence is limited, early preclinical results suggest exosome treatment may enhance hair growth and warrant further research for therapeutic use in alopecia.

This review reports that oral collagen peptide supplements may improve skin elasticity, hydration, and wrinkle appearance while also supporting hair and nail health and wound healing, but emphasizes the need for longer, high-quality studies due to current research limitations and variability in findings.

In this comprehensive review, researchers reported that macromolecules like type I collagen, keratin, and ceramides enhance hair health by improving follicular function and increasing hair density, strength, shine, and resilience, as shown in various in vitro, animal, and human studies.

In this study, researchers found that mangosteen pericarp extract, combined with FeSO₄ as a mordant, effectively produced a stable reddish hair dye on bleached hair, with good color persistence and enhanced tensile strength, indicating its potential as an eco-friendly and safer alternative to synthetic dyes.

In this pilot randomized clinical trial, TRT combined with finasteride increased lean mass, muscle size, and bone mineral density without prostate enlargement in men with spinal cord injury, suggesting potential benefits for body composition and musculoskeletal health.

This review highlights the lack of research on Afro-textured hair, emphasizing the need for better understanding of its genetic traits and molecular structure to develop more effective hair care solutions.

In this study, researchers observed that even a single session of hair dyeing can damage hair fibers, with significant worsening of mechanical properties and protein composition after three or more consecutive treatments, emphasizing the need to consider the cumulative impacts of dyeing on hair health.

This study found that Platycladus orientalis flavonoids may reduce oxidative damage and slow melanin degradation in AGA-affected hair, improving its quality.

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 study found that the NuMA protein's microtubule-binding domain is essential for proper spindle orientation and differentiation in keratinocytes, affecting skin and hair development in mice.

This study reported that three months of platelet-rich plasma injections improved hair counts, thickness, root strength, and overall alopecia in patients with androgenic alopecia, with no major adverse effects.

This study developed a bilayer material combining poly(vinyl alcohol) and bacterial cellulose with a gelatin-poly(vinyl alcohol) hydrogel, showing strong potential as a wound dressing due to its good antibacterial properties, cell viability, and sustained drug release.

This study proposed a new standardized in vitro framework using human hair tresses to evaluate cosmetic hair product performance and found significant improvements in hair breakage, tensile strength, shine, volume, and frizz control compared to a control group without such changes.

In a laboratory study, researchers found that a novel Bioactive Crosslink Repair Complex improved both the protection and repair of chemically damaged hair, enhancing tensile strength, shine, and cuticle alignment when added to bleaching mixtures and leave-in conditioners.

This study found that for straight hair, friction mainly influences fragment formation during combing, suggesting no direct connection to tensile fatigue failure, while with textured hair, combing performance may be more complex.

This study reported that fermented grapeseed oil may enhance hair permeability and improve strength and color retention in chemically treated hair compared to regular grapeseed or silicone oils.

This study found that novel thiol-reactive cross-linking agents, particularly APA, significantly improved the tensile strength and elasticity of human hair fibers by effectively regenerating disulfide bridges, with potential applications for advanced hair repair treatments in the cosmetic industry.
