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 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 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 A novel cosmetic approach to treat thinning hair
A new hair treatment with caffeine and other ingredients makes hair thicker and less likely to break.
research Nanomechanical characterization of human hair using nanoindentation and SEM
Human hair's strength and flexibility vary by ethnicity, damage, and treatment.

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 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 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 Microscopic high-resolution digital volumetric imaging of human hair fibers
DVI provides detailed 3D imaging of hair and shows how various products protect and enhance hair.
research Porosity at Different Structural Levels in Human and Yak Belly Hair and Its Effect on Hair Dyeing
Yak belly hair has higher porosity and is less stiff than human hair, making it absorb dye better but less suitable as a direct substitute for hair dyeing.
research Biomechanical properties of scalp flaps and their correlations to reconstructive and aesthetic surgery procedures
Scalp flaps are stiffer than skin from other body areas, which helps in planning reconstructive and cosmetic head surgeries.
research Physical Properties of Human Hair. 1. Evaluation of Bending Stress by Measuring the Major and the Minor Axis of Human Hair.
The cuticle significantly contributes to hair stiffness, making up about 60% of the total bending stress.
research Optimizing Hyaluronic Acid: A Comprehensive Review of Rheological Insights for Clinical Practice
Understanding the properties of hyaluronic acid helps improve its use in facial aging treatments.
research A new approach to the bending properties of hair fibers.
The new test shows how hair treatments affect hair's bending stiffness by swinging a pendulum through hair fibers.
research The Physical Properties of Hair Fibers

research Comparing Protective Pre-treatments for African Hair
Plant oils and polymers can help protect African hair from damage during styling.
research Chapter 4 Cytomechanics of Hair
Hair's strength and flexibility come from its protein structure and molecular interactions.
research Curly hair: measured differences and contributions to breakage
Curly hair breaks more easily, especially with chemical treatments, but simpler grooming reduces breakage.
research Qualification of a new and precise automatic tool for the assessment of hair diameters in phototrichograms
The new automatic tool accurately measures hair thickness and is reliable.
research Hair greying is associated with active hair growth
White hair grows thicker and faster than black hair due to higher activity of growth-related genes and proteins.
