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 The susceptibility of disulfide bonds to modification in keratin fibers undergoing tensile stress
Disulfide bonds in keratin fibers break more easily under stress, especially when wet, affecting fiber strength.
research Hair-on-hair static friction coefficient can be determined by tying a knot
Tying a knot can measure hair friction, useful for medical applications.
research Topological Distribution of Wound Stiffness Modulates Wound-Induced Hair Follicle Neogenesis
The stiffness of a wound affects hair growth during healing, with less stiff areas growing more hair.
research Monitoring of Wool Stretching Process Using Polarized Second Harmonic Generation
Stretching wool changes its structure and improves fiber alignment.
research Micro-mechanical approaches to characterize tip growth: Insights into root hair elasto-viscoplastic properties
Root hair growth mechanics depend on turgor pressure and cell wall properties.
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 Symmetry breaking of tissue mechanics in wound induced hair follicle regeneration of laboratory and spiny mice
Tissue stiffness affects hair follicle regeneration, and Twist1 is a key regulator.
research 439 Gradients of Mesenchymal Stiffness Control Sweat Gland Cell Fate Specification During Morphogenesis
Mesenchymal stiffness affects sweat gland cell development.
research Multiscale modelling of human hair
Human hair becomes weaker and stretches more easily at higher temperatures.
research Understanding Curly Hair Mechanics: Fiber Strength
Curly hair is mechanically different from straight hair and may need new testing methods.
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 Development of a three‐point cantilever bending technique to study the mechanical properties of hair styling ingredients
The technique helps measure how hair styling ingredients affect hair's stiffness and flexibility.
research The frictional properties of wool and related hair fibers.
research [A longitudinal elasticity study of hair from the human head in forensic medicine].
The method effectively measures hair elasticity and could be useful in forensics.
research Hair-on-hair static friction coefficient can be determined by tying a knot B Biointerfaces
Treating hair with 1M sodium hydroxide increases its friction, making it better for small medical knots.
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 Characterization of murine excisional wounds based on atomic force microscopy indentation
Murine skin wounds become less stiff over time as they heal.
research Torsional behavior of human hair
Water makes hair more flexible, especially the outer layer.
research Multiple sclerosis disease-modifying therapies: adverse effect surveillance and management
The document concludes that managing side effects of MS therapies is crucial for treatment success and patient adherence.
research Clinical, trichoscopic, and histological characteristics of 46 hispanic men with fibrosing alopecia in a pattern distribution: a retrospective multicenter analysis
Fibrosing alopecia starts earlier in Latin American men and often looks like common male pattern baldness.
research Expanding the Senior-Løken syndrome spectrum: Combined Rothmund-Thomson features unveil the distinct Teelwani Syndrome phenotype
A new syndrome, Teelwani Syndrome, combines features of two rare genetic disorders.
research Alopecia Areata Associated with Dupilumab: A Case Report and Literature Review
Dupilumab may cause hair loss, so patients should be monitored.
research A comparative assessment of propranolol, flunarizine and divalproex sodium in prophylactic therapy of migraine in a teaching Hospital in North India
Propranolol, flunarizine, and divalproex sodium are equally effective for preventing migraines, but have different side effects.
research Trichostasis Spinulosa of the Heel: Unique Presentation with Characteristic Morphology
A rare skin condition usually on the face was found on a man's heel.
research Pulling force deforms hair follicle root sheath nuclei and surrounding dermal collagen matrix differently at infundibulum, isthmus and suprabulbar regions
Hair follicles respond differently to pulling forces in various regions.
research Mechanism research of yak hair stretching slenderization based on the changes of conformation and cell shape
Yak hair stretches mainly due to macromolecules slipping past each other.
research Cutaneous Toxicities From Transplantation-Related Medications
Skin problems from transplant drugs are common and need careful management in organ transplant patients.
research Perifollicular vascularization: Cocultures and tricultures approaches to study the cross-talk between microvascular endothelial cells, follicle papilla cells and keratinocytes
Hair papilla cells are crucial for blood vessel development in hair follicles, affecting hair growth and loss.
