research Chapter 4 Cytomechanics of Hair
Hair's strength and flexibility come from its protein structure and molecular interactions.
research Correlation between element concentrations and x‐ray diffraction patterns in hair
Elemental composition of hair affects its x-ray diffraction patterns.
research Structural analysis of human hair single fibres by scanning microbeam SAXS
Hair curliness is due to uneven distribution of different cortices within the hair fiber.
research Cryo-Electron Microscopy of Trichocyte (Hard α-Keratin) Intermediate Filaments Reveals a Low-Density Core
Trichocyte filaments have a low-density core and may include proteins for hair structure.

research Evolutionary Trees of Intermediate Filament Proteins
research Crystal structure of Steroid 5-alpha-reductase 2 in complex with Finasteride
research Azimuthal Scattering from Elliptical Hair Fibers
Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.
research Reimagining Hair Science: A New Approach to Classify Curly Hair Phenotypes via New Quantitative Geometrical & Structural Mechanical Parameters
New methods to classify curly hair types were developed based on shape and strength.
research X-rays studies of the structure of hair, wool, and related fibres. II. - The molecular structure and elastic properties of hair keratin
Stretched hair has a similar structure to natural silk, showing hair's elasticity involves reversible changes within its molecules.
research Fracture in Hierarchical Biomaterials: Human Hair
Human hair's structure makes it tough and resistant to breaking.
research An mTurq2-Col4a1 mouse model allows for live visualization of mammalian basement membrane development
The mTurq2-Col4a1 mouse model shows how the basement membrane develops in live mammals.
research Structure and Mechanical Properties of Human Trichocyte Keratin Intermediate Filament Protein
Disulfide bonds make keratin in hair stronger and tougher.
research Small animal models of thermal injury
research Structure of intermediate filament assembly in hair deduced from hydration studies using small-angle neutron scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
research Effect of disulfide bonds in human hair fibers on the melting behavior of their crystalline structure
Disulfide bonds affect the melting behavior of hair's crystalline structure, but hair retains some stability even after these bonds are broken.
research μ-Crystallin, Thyroid Hormone-binding Protein, is Expressed Abundantly in the Murine Inner Root Sheath Cells
μ-Crystallin may help hair growth by affecting thyroid hormone levels in mouse hair follicles.
research Fractal geometry and topology abstracted from hair fibers
Hair fibers have fractal patterns with properties related to the golden mean, which may affect their functionality.
research In vitro strategies for mimicking dynamic cell–ECM reciprocity in 3D culture models
The conclusion is that accurately replicating the complexity of the extracellular matrix in the lab is crucial for creating realistic human tissue models.
research Exploring a biological tissue from atomic to macroscopic scale using synchrotron radiation: example of hair.
Hair has unevenly distributed proteins and lipids, with lipids mainly in the cuticle and proteins in the cortex and medulla.
research Isolation of intermediate filament assemblies from human hair follicles.
Researchers isolated and identified structural components of human hair follicles, providing a model for studying hair formation.
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.
