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 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 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 Evaluation method of the degree of hair damage. (I). Measurement of tensile strength of human hair by "the multi-point tension test method".
The method accurately measures hair damage and strength, revealing effects of cosmetics and metal correlations.
research Fiber-Safe Extraction of Red Mordant Dyes from Hair Fibers
Researchers developed a less damaging way to extract red dyes from wool using EDTA and DMF, preserving the fiber's strength for further analysis.
research Studies of light scattering from ethnic hair fibers
Different hair types from various ethnic groups affect hair shine due to characteristics like thickness and shape.
research In situ tensile deformation characterization of human hair with atomic force microscopy
AFM helped show how hair changes under tension and the effects of damage and conditioner.
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 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 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 Impact of acid straightener's pH value in the hair fiber properties
Lower pH straighteners change hair more but weaken it.
research Development of predictive regression model for perceived hair breakage in Indian consumers
The model predicts hair breakage based on key hair properties and helps product developers.
research Biomechanics of chemically treated hair for continuous 1D strands
NaOH treatment improves hair strength and suitability for textiles.
research Possible relationships between the physical conditions of cattle and the occurrence of structural modifications of their coat hair
Vitamin A deficiency changes cattle hair structure, while pregnancy may improve it, suggesting hair can indicate cattle health.
research Effect of Temperature and Humidity on Mechanical Properties of Rabbit Hair Fibers
Higher temperatures improve rabbit hair strength up to 50°C, but moisture weakens it.
research Analysis of structural changes in permanent waved human hair using Raman spectroscopy
Permanent waving weakens hair by altering its protein structure.
research Protein disulphide isomerase-mediated grafting of cysteine-containing peptides onto over-bleached hair
PDI helps restore over-bleached hair's strength and structure by attaching special peptides.
research Development and evaluation of hair mask formulations containing vegetable oils from Brazilian biodiversity for curly hair
Pequi and buriti oils improve curly hair's gloss and strength.
research Dataset from the uniaxial tensile testing of human curly hair fibers under different conditions
Curly hair's strength and flexibility vary with moisture and temperature.
research Understanding Curly Hair Mechanics: Fiber Strength
Curly hair is mechanically different from straight hair and may need new testing methods.
research Hair Mechanical Properties Depending On Age And Origin
Hair properties vary with age and ethnic origin.
research Giant axonal neuropathy alters the structure of keratin intermediate filaments in human hair
Giant axonal neuropathy changes the structure of keratin in human hair.
research Electrospun Scaffold of Collagen and Polycaprolactone Containing ZnO Quantum Dots for Skin Wound Regeneration
The new wound dressing helps skin heal faster and fights infection.
research Penetration of different molecular weight hydrolysed keratins into hair fibres and their effects on the physical properties of textured hair
Different sizes of keratin peptides can strengthen hair, with smaller ones possibly increasing volume and larger ones repairing damage.
research Protective and Restorative Effects of a Bio-Based Crosslinking Complex on Chemically Damaged Hair
The bio-based complex effectively repairs and protects chemically damaged hair.
research Cyclic combing of untreated and bleached human hair: Analysis of the time‐dependent breakage of hair through recording the formation of fibre fragments
Friction causes hair breakage during combing, and fragment count predicts hair strength.
research Novel Compounds for Hair Repair: Chemical Characterization and In Vitro Analysis of Thiol Cross-Linking Agents
APA is a promising new compound for repairing damaged hair, outperforming Olaplex® in strength and elasticity.
research Quantifying the effects of repeated dyeing: morphological, mechanical, and chemical changes in human hair fibers
Repeated hair dyeing significantly damages hair.
research Bleached Hair as Standard Template to Insight the Performance of Commercial Hair Repair Products
K18® and Olaplex® both effectively repair bleached hair, improving its strength, smoothness, and overall health.
