research Skin care during the menopause period: noninvasive procedures of beauty studies
The conclusion is that a combination of noninvasive treatments and lifestyle changes can improve skin health during menopause.
research Genetic correlation analysis does not associate male pattern baldness with COVID-19
There's no significant genetic link between male pattern baldness and COVID-19.
research Culture of pyramidal neural precursors, neural stem cells, and fibroblasts on various biomaterials
Different materials affect the growth of brain cells and fibroblasts, with matrigel being best for brain cell growth.
research Androgenic modulation of arterial baroreceptor dysfunction and neuroinflammation in endotoxic male rats
Testosterone affects blood pressure control and inflammation in male rats with endotoxic shock, and blocking certain hormones may help treat it.
research Insights into anthropogenic threats and early mortality in the Guadalupe fur seal from a plausible mixed colony on the San Benito Archipelago, Mexico
Guadalupe fur seals at San Benito Archipelago face high mortality and health issues due to pollution and marine debris.
research Orchid callus extract: a sustainable and natural active to promote hair growth
Orchid callus extract can help hair grow and may be used in eco-friendly hair products.
research Robust coupling between the C‐tactile afferent and the hair follicle in humans
C-tactile nerves are sensitive to hair movement.
research INTRODUCING THEORY LINKING GENESIS OF HAIR SHAFT BIPOLARITY WITH ARRECTOR PILI MUSCLE PROXIMAL ATTACHMENT
The document suggests that human hair has electrical charges because of a gap in nerve cell coverage that affects electromagnetic radiation.
research It's not all traction: the pseudo ‘fringe sign’ in frontal fibrosing alopecia
The pseudo 'fringe sign' can also appear in frontal fibrosing alopecia, not just in traction alopecia, showing that this condition may be more common than thought.
research Effect of ethnicity and treatments on in situ tensile response and morphological changes of human hair characterized by atomic force microscopy
Different ethnicities and treatments affect human hair strength and structure.
research Cyclic combing of untreated and bleached human hair: Analysis of the time‐dependent breakage of hair through recording the formation of fibre fragments
Friction causes hair breakage during combing, and fragment count predicts hair strength.
research Overactive Wnt5a signaling disrupts hair follicle polarity during mouse skin development
Overactive Wnt5a disrupts hair follicle orientation in mice.
research Influence of functionalized silicones on hair fiber–fiber interactions and on the relationship with the macroscopic behavior of hair assembly
Functionalized silicones improve hair appearance, combing, and manageability.
research Direct evidence supporting the existence of a helical dislocation in protofilament packing in the intermediate filaments of oxidized trichocyte keratin
Oxidized trichocyte keratin has a helical dislocation in its structure.
research Spider joint hair sensilla: adaptation to proprioreceptive stimulation
Spider joint hair sensilla are adapted to sense movement during walking.
research Scattering from Elliptical Hair Fibers Based on Microfacet Theory
research Club-like receptors respond to light touch but not to whisking
Club-like receptors detect light touch but not whisking.
research Multiscale modelling of human hair
Human hair becomes weaker and stretches more easily at higher temperatures.
research Analyzing the laser-light reflection from human hair fibers. I. Light components underlying the goniophotometric curves and fiber cuticle angles.
The research found a way to measure hair surface changes by analyzing how light reflects off of it, and determined hair cuticle angles vary by hair length and color.
research ToF‐SIMS characterization of the lipid layer on the hair surface. II : Effect of the 18‐MEA lipid layer on surface hydrophobicity
18-MEA is essential for hair's water resistance, and a conditioner with 18-MEA and SPDA can restore it.
research Impact of acid (”progressive brush”) and alkaline straightening on the hair fiber: Differential effects on the cuticle and cortex properties
Glyoxylic acid straighteners cause more protein loss but have similar hair strength effects as traditional alkaline straighteners.
research Exploring the Effects of Wetting and Free Fatty Acid Deposition on an Atomistic Hair Fiber Surface Model Incorporating Keratin-Associated Protein 5-1
Damaged hair allows water to penetrate more easily, and fatty acids from shampoos can deposit on hair surfaces.
research Micro-mechanical approaches to characterize tip growth: Insights into Root Hair Elasto-Viscoplastic Properties
Root hair stiffness is mainly influenced by tip compression and turgor pressure.
research Effect of the degree of acetylation on the physicochemical properties of α-chitin nanofibers
Lower acetylation makes chitin nanofibers thinner and more suitable for various uses.
research The Role of Interface Geometry and Appendages on the Mesoscale Mechanics of the Skin
Skin's uneven surface and hair follicles affect its stress and strain but don't change its overall strength, and help prevent the skin from peeling apart.
research Influence of Ethnic Origin of Hair on Water-Keratin Interaction . . . . . . . . . . . . . . . . . . . . . . . Alain Franbourg, Fre´de´ric Leroy, Marielle Escoube´s, and
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 Pattern formation on regular polygons and circles
Domain shape greatly affects pattern formation.
research Understanding Curly Hair Mechanics: Fiber Strength
Curly hair is mechanically different from straight hair and may need new testing methods.
