research Quasi-Static Torsional Deformation of Single Hair Fibers: Application of a Modeling Approach and Results from Cosmetic Treatments.
The research found that twisting hair fibers can show changes in stiffness and damage, and help tell apart different hair treatments.
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 Characterization of the mechanical properties of the cortex region of human hair fibers by multiparametric Atomic Force Microscopy mapping
Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.
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 Hyaluronic acid: elucidating its penetration into, and effect on hair fibers using confocal Raman spectroscopy and biometric techniques
Hyaluronic acid in shampoo penetrated hair well, reduced frizz, and improved hair strength and moisture.
research Some Tensile Properties of Specialty Hair Fibers
Animal hair fibers like wool and mohair are strong when dry, but vicuna fibers are very brittle.
research Mechanical properties characterization of human hair fibers cortex region by multiparametric Atomic Force Microscopy mapping
The active ingredient improves the strength of damaged hair fibers.
research Alignment control and softness creation in hair with glycylglycine.
Glycylglycine makes hair softer by improving alignment and changing hair's internal properties.
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 Nanomechanical characterization of human hair using nanoindentation and SEM
Human hair's strength and flexibility vary by ethnicity, damage, and treatment.
research Effect of anti-keratin antibody on the nature of hair
Anti-keratin antibody from cow milk makes damaged hair stronger and less likely to break.
research Tensile properties of twisted hair fibers
Twisting hair weakens it, but strength can be recovered at low twist levels.
research Reproduction Mechanism of SS Cross-Links in Permed Hair by the Washing after Reduction with Thioglycolic Acid
Washing permed hair after using thioglycolic acid helps reform strong bonds, making hair stronger.
research Evaluation of hair humidity resistance/moisturization from hair elasticity.
Polyquaternium-70 shampoo is best for reducing frizz.
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 Regenerating Hair in Prevascularized Tissue Space Formed by a Controllable Foreign Body Reaction
The new method grows more hair than traditional methods.
research The 'self recovery phenomenon' of oxidized hair
Oxidized hair can naturally regain strength and stability over six months.
research Biomechanics of chemically treated hair for continuous 1D strands
NaOH treatment improves hair strength and suitability for textiles.

Hair follicles and skin structures were successfully regenerated in the lab using specific cell arrangements and mechanical conditions.
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 Natural ‘Green’ Sugar-Based Treatment for Hair Styling
Scientists created a non-toxic, sugar-based hair product that can style hair without damage.
research Single hair fiber assessment techniques to discriminate between mineral oil and coconut oil effect on hair physical properties
Coconut oil makes hair stronger and more flexible than mineral oil.
research Interactions between Crossed Hair Fibers at the Nanoscale
Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.
research Systems Approach to Human Hair Fibers: Interdependence Between Physical, Mechanical, Biochemical and Geometric Properties of Natural Healthy Hair
Hair properties are interconnected; a comprehensive, cross-disciplinary approach is essential for understanding hair behavior.
research How different is human hair? A critical appraisal of the reported differences in global hair fibre characteristics and properties towards defining a more relevant framework for hair type classification
Human hair varies widely and should be classified by curl type rather than race.
research Volume Changes During Water Binding to Hair Fibers
Hair increases in size when it absorbs water, and treatments like bleaching affect how much water it can take in.
research A reciprocal lattice approach to assessing the luster of hair fibers, based on scattering by periodically deformed cylinders
A new method helps understand hair shine and various products improve hair care.
research Action of Thioglycolic Acid and L-Cysteine to Disulfide Cross-Links in Hair Fibers during Permanent Waving Treatment
Thioglycolic acid and L-cysteine change hair structure differently during perms, affecting hair strength and curling efficiency.
research The effect of relative humidity on the spreading of ethanol on human hair fibers
Ethanol spreads well on hair at low humidity but less so at higher humidity due to water condensation.
