research Stiffness of Human Hair Correlates with the Fractions of Cortical Cell Types
Hair stiffness is higher when it has more para-like cortical cells.
research Characterization of hair lipid and protein dynamics using EPR spectroscopy and treatment effects
Hair treatments and dehydration affect hair's lipid and protein behavior, influencing its flexibility and appearance.
research A Raman spectroscopy investigation of the resilience of hair cuticular scales under uniaxial stress
research 877 Integration of magnetic tweezers and traction force microscopy for exploring the mechanobiology of keratinocyte cell-cell and cell-matrix anchoring junctions
The conclusion is that a new method combining magnetic tweezers and traction force microscopy may help understand skin cell interactions and diseases.
research Analysis of slenderizing human hair fibers surface morphology
research Nanoindentation of Hair Cortex and Medulla Regions
research Keratin network modifications lead to the mechanical stiffening of the hair follicle fiber
Changes in keratin make hair follicles stiffer.
research Homogenization theory captures macroscopic flow discontinuities across Janus membranes
The homogenization theory effectively describes how flow behaves differently across asymmetric membranes.
research Impact of acid straightener's pH value in the hair fiber properties
Lower pH straighteners change hair more but weaken it.
research Hair curvature: a natural dialectic and review
The document concludes that hair curvature can be explained by the growth patterns caused by the shape and separation of cells in the hair follicle and is affected by specific molecular pathways.
research Influence of particle parameters on deposition onto healthy and damaged human hair
Particles stick better to healthy hair than damaged hair.
research The effect of treatments on the shear modulus of human hair measured by the single fiber torsion pendulum.
Different treatments change the strength and flexibility of human hair.
research The toughening transition in hair keratin
The observed "toughening" in keratin was actually due to water evaporation, not a real change in keratin.
research In vivo silica nanoparticle translocation across human stratum corneum: the effect of surface hydrophobization in relation to hair follicle density.
Hydrophobized silica nanoparticles penetrate the skin's outer layer more effectively, while hair follicle density doesn't impact their accumulation.
research Comments on ‘Strength and Deformation Behavior of Fine-Grained Soils Reinforced with Hair Fibers and Its Application in Pavement Design’ by Ayothiraman et al. [Journal of Natural Fibers, DOI: 10.1080/15440478.2021.1954129]
research A pilot study on the sexual side effects of finasteride as related to hand preference for men undergoing treatment of male pattern baldness
Left-handed men experience more sexual side effects from finasteride treatment.
research Natural swing frequency of human hair - a novel method to quantify natural hair collective movements
Human hair movement is affected by its inner structure and chemical treatments.
research Effect of Rubbing Application on the Skin Permeation of Active Ingredients from Lotion and Cream
Rubbing skin increases absorption of water-soluble drugs from lotions and creams, but not oil-soluble drugs.
research Single Root hair growth under constant force: insights into wall mechanics
Root hair growth slows under force, confirming a model of cell wall mechanics.
research Order from disorder: Self-organization in mammalian hair patterning
Hair patterns in mice are controlled by both a global system dependent on Fz6 and a local self-organizing system.
research Torsional method for evaluating hair damage and performance of hair care ingredients
The torsional method effectively evaluates hair damage and the performance of hair care ingredients.
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 Failure of intercellular adhesion in hair fibers with regard to hair condition and strain conditions
Hair breaks differently when wet or dry and is affected by its condition and treatments like perms and bleaching.
research Effect of Rubbing Application on the Skin Permeation of Active Ingredients from Lotion and Cream
Rubbing lotion or cream increases caffeine absorption through the skin but not rhododendrol.
research Insights on the mechanical behavior of keratin fibrils
Keratin's mechanical properties are influenced by hydrogen bonds and secondary structure, and can be improved with the SPD-2 peptide.
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 Effect of Waste Human Hair Fibers on Shear Behavior of Sand in Dry and Saturated Conditions
Adding human hair to sand improves its strength when dry and maintains strength when wet.
research The effect of relative humidity on the spreading of ethanol on human hair fibers
Ethanol spreads well on hair at low humidity but less so at higher humidity due to water condensation.
