research Effect of equilibrium pH on the structure and properties of bleach‐damaged human hair fibers
Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.
research Regulation of hard α-keratin mechanics via control of intermediate filament hydration: matrix squeeze revisited
Hard α-keratins stay stiff in water because the surrounding matrix keeps them dehydrated and strong.
research Combination of Transcriptomics and Proteomics Reveals Differentially Expressed Genes and Proteins in the Skin of EDAR Gene-Targeted and Wildtype Cashmere Goats
Deleting the EDAR gene in Cashmere goats affects genes and proteins related to hair growth.
research Development of a mechanically stable human hair keratin film for cell culture
A new film made from human hair supports skin cell growth better than collagen.
research Insights on the mechanical behavior of keratin fibrils
Keratin's mechanical properties are influenced by hydrogen bonds and secondary structure, and can be improved with the SPD-2 peptide.
research Stiffness of Human Hair Correlates with the Fractions of Cortical Cell Types
Hair stiffness is higher when it has more para-like cortical cells.
research Age, lifestyle and self‐perceptions of hair: Is there an association with hair diameter and tensile properties?
Older age and certain lifestyles are linked to thinner, weaker hair, while how you see your hair relates to its thickness.
research Investigating the relationship between the hair fiber proteome and hair quality
Hair quality is genetically determined and linked to its composition and strength.
research Biomechanics of chemically treated hair for continuous 1D strands
NaOH treatment improves hair strength and suitability for textiles.
research Coordination of force-generating actin-based modules stabilizes and remodels membranes in vivo
Actin filaments help stabilize and reshape cell membranes.
research Nanomechanical characterization of human hair using nanoindentation and SEM
Human hair's strength and flexibility vary by ethnicity, damage, and treatment.
research Enhancing properties of damaged hair through moisture control via construction of highly hydrophobic surface
A silicone treatment makes damaged hair more water-resistant and stronger.
research Natural ‘Green’ Sugar-Based Treatment for Hair Styling
Scientists created a non-toxic, sugar-based hair product that can style hair without damage.
research Tensile properties of twisted hair fibers
Twisting hair weakens it, but strength can be recovered at low twist levels.
research Leveraging Crosslinker Diffusion to Template Stiffness Gradients in Alginate Hydrogels
Stiffness gradients in alginate gels can guide cancer cell invasion and study cellular behaviors.
research TENSILE STRENGTH OF SCALP HAIR IN WOMEN WITH HAIR LOSS
Women with hair loss have weaker hair that breaks more easily.
research Effect of ethnicity and treatments on in situ tensile response and morphological changes of human hair characterized by atomic force microscopy
Different ethnicities and treatments affect human hair strength and structure.
research Effect of varied hair protein fractions on the gel properties of keratin/chitosan hydrogels for the use in tissue engineering
Different hair protein amounts change the strength of keratin/chitosan gels, useful for making predictable tissue engineering materials.
research Structural Abnormalities in the Hair of a Patient with a Novel Ribosomopathy
The patient's hair was thinner and had fewer lipids due to a genetic mutation.
research Disulfide Cross-Linked Network Structure of Intermediate Filament and Matrix in Hair and Wool Cortices
Hair and wool strength is affected by the number and type of bonds in their protein structures, with hair having more protein aggregates than wool.
research Chemical bonds and hair behaviour—A review
Disulfide bonds are crucial for hair's strength, especially when wet.
research The susceptibility of disulfide bonds to modification in keratin fibers undergoing tensile stress
Disulfide bonds in keratin fibers break more easily under stress, especially when wet, affecting fiber strength.

5% hydroxyapatite in scaffolds improves bone tissue formation and mechanical properties.
research Fabrication of Bioactive Helix aspersa Extract-Loaded Chitosan-Based Bilayer Wound Dressings for Skin Tissue Regeneration
Snail secretion-loaded dressings can improve skin regeneration and wound healing.
research Comparing Protective Pre-treatments for African Hair
Plant oils and polymers can help protect African hair from damage during styling.
research In-Silico Modelling of Transdermal Delivery of Macromolecule Drugs Assisted by a Skin Stretching Hypobaric Device
The simulation showed that hypobaric pressure improves drug delivery through the skin, but stretching alone doesn't fully explain the increase.
research Exploring the role of two polypeptide nanofiber gels derived from RADA16-I self-assembly in accelerating burn wound healing
