The model helps improve medical devices by showing how skin deforms under pressure.
research The Intermediate Filament Architecture as Determined by X-Ray Diffraction Modeling of Hard α-Keratin
Hard α-keratin in hair has a unique, nonordered structure, different from other fibers.
research Tactile and hair-hair friction behavior of hair fibers
Hair feels different when touched and rubs together in various ways.
research Standardization of Trichotillometer
Trichotillometry can measure hair plucking force, aiding alopecia treatment evaluation.

The alpha-helix was confirmed as a key structure in proteins.
research Structural interspecies variability of mammals' hairs
Mammal hairs have different internal structures.
research Clinical, Tricoscopic and Histopathological Findings in Mexican Women with Traction Alopecia
Changing certain hairstyles can prevent worsening hair loss in Mexican women.
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 Correlation of monosynaptic field potentials evoked by single action potentials in single primary afferent axons and their bouton distributions in the dorsal horn
The study found that nerve signals are stronger when there are more connection points, but not necessarily denser, along the nerve's path in the spine.
research Optical coherent tomography: promising in vivo measurement of hair shaft cross section
OCT is a reliable, noninvasive way to measure hair thickness.
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 The trichotillometry: a technique for hair assessment
Trichotillometry is a reliable method to measure hair strength and assess hair loss treatments.
research Chirality Effect on Physical and Biological Properties of Peptide-Based Hydrogels
Chirality affects the structure, strength, and function of peptide-based hydrogels.

Björnstad syndrome causes twisted hair from birth.
research An ultrastructural study on corkscrew hairs and cigarette‐ash‐shaped hairs observed by dermoscopy of tinea capitis
Corkscrew and cigarette-ash-shaped hairs in tinea capitis are caused by internal hair degradation and external resistance.
research MULTIPLE DEFECTS OF THE HAIR SHAFT IN NETHERTON'S DISEASE.
Netherton's disease causes multiple hair defects.
research Faculty Opinions recommendation of Symmetry breaking of tissue mechanics in wound induced hair follicle regeneration of laboratory and spiny mice.
research Determinants of marginal traction alopecia in African girls and women
Traction alopecia is more common in African women than girls, especially when traction is applied to chemically relaxed hair; avoiding such hairstyles may reduce the risk.

Chemical hair straightening changes hair proteins and mostly fixes broken bonds.
research Self-consistent field theory for the interactions between keratin intermediate filaments
Keratin filaments' elasticity is influenced by their terminal domains and surrounding medium.

Black holes with primary Proca hair can have unique shadows with inner rings, affecting how we observe them.
research Rapunzel! Rapunzel! How Strong Is Your Hair?
Hair can't be as strong as Rapunzel's because it's impractical to scale up due to defects.
research TENSILE STRENGTH OF SCALP HAIR IN WOMEN WITH HAIR LOSS
Women with hair loss have weaker hair that breaks more easily.
research Improved two‐dimensional electrophoretic mapping of Japanese human hair proteins; application to curved and straight Japanese human hairs; and protein identification by MALDI MS and MS/MS quadrupole time‐of‐flight mass spectrometry
