Different ethnicities and treatments affect human hair strength and structure.
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 Triboelectric Microcapsules for Spatially Adaptive Electroceutical Therapy and Scarless Skin Regeneration
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 Role of calcium and other ions in directing root hair tip growth
Calcium and hydrogen ions help root hair growth, while aluminum inhibits it.
research Immunolocalization of junctional proteins in human hairs indicates that the membrane complex stabilizes the inner root sheath while desmosomes contact the companion layer through specific keratins
Junctional proteins stabilize the inner root sheath and connect the companion layer in human hair.
research Introducing Exogenous Energy From Hydrocolloid Wound Dressing Disrupting Human Hair Follicle Metabolism
Hydrocolloid wound dressings emit energy that can affect human hair follicle metabolism.
research Multifunctional Merkel cells: Their roles in electromagnetic reception, finger-print formation, Reiki, epigenetic inheritance and hair form
Merkel cells may have roles in sensing magnetic fields, creating fingerprints, Reiki energy healing, passing on environmental information to offspring, and influencing hair shape.
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 Heterotypic cell contacts and basal lamina morphology during hair follicle development in the mouse: a light, scanning, and electron microscopic study at the site of tissue interaction
Heterotypic cell contacts likely help hair matrix cells differentiate during mouse hair follicle development.
research Electrical stimulation to human dermal papilla cells for hair regenerative medicine
Electric stimulation can increase hair growth by activating certain genes in skin cells.
research Scattering from Elliptical Hair Fibers Based on Microfacet Theory
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
The study found that minor protein differences between curved and straight Japanese hair are unlikely to significantly affect hair structure.
