research Local Structure of Human Hair Spatially Resolved by Sub-Micron X-Ray Beam
Human hair has a new region with ordered filaments and the cuticle contains β-keratin sheets.
research Structure of Intermediate Filament Assembly in Hair Deduced from Hydration Studies Using Small-Angle Neutron Scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
research Advances in the Chemical Structure of the Hair Surface, Surface Forces and Interactions
Understanding hair surface properties is key for effective hair care products.
research Hair Cuticle Differences Between Asian And Caucasian Females
Asian hair is stronger and more damage-resistant than Caucasian hair due to a thicker cuticle layer.
research Investigation of the Changes in the Hair Cuticle Due to Chemical Degradation
Chemical treatments severely damage hair cuticles, especially in previously treated hair.
research Microanatomical Observations of Hair Characteristics of Red Fox (Vulpes Vulpes), Golden Jackal (Canis Aureus), and Gray Wolf (Canis Lupus): A Comparative Study
Red fox, golden jackal, and gray wolf hairs have similar features but differ in length, thickness, and inner structure.
research Variation in Human Hair Ultrastructure Among Three Biogeographic Populations
Different populations have distinct hair structures related to their ancestry.
research In Situ Tensile Deformation Characterization of Human Hair with Atomic Force Microscopy
AFM helped show how hair changes under tension and the effects of damage and conditioner.
research Topographical and Tribological Characteristics of Asian Human Hair Cuticles
Hair damage increases significantly with higher temperatures and longer heating times.
research Evaluation of Polymethylene Waxes as Conditioning Agents in Hair Relaxers
Polymethylene wax in hair relaxers makes hair smooth and shiny with less damage.
research Histochemical Observation of the Cell Membrane Complex of Hair
The Cell Membrane Complex in hair has both water-attracting and water-repelling layers.
research Quantifying the Effects of Repeated Dyeing: Morphological, Mechanical, and Chemical Changes in Human Hair Fibers
Repeated hair dyeing significantly damages hair.
research Cosmetic Approach for Healthy and Damaged Hair
Cosmetic procedures can harm hair, but damage can be minimized with knowledge and care; however, once hair is damaged, it cannot be reliably repaired.
research Effect of Shampoo, Conditioner, and Permanent Waving on the Molecular Structure of Human Hair
Perming significantly changes hair's molecular structure, while shampoo and conditioner do not.
research Evaluation of Surface Structure and Morphological Phenomena of Caucasian Virgin Hair with Atomic Force Microscopy
AFM can diagnose hair disorders by revealing detailed hair surface changes.
research Hair Lipid Structure: Effect of Surfactants
Surfactants in shampoos and conditioners remove some but not all lipids from hair, and more research is needed to understand their full impact.
research Electron Microscope Studies of Hair and Wool
Hair and wool have complex microscopic structures with microfibrils and varying cystine content.
research Protein Disulfide Isomerase-Mediated Grafting of Cysteine-Containing Peptides onto Over-Bleached Hair
PDI helps restore over-bleached hair's strength and structure by attaching special peptides.
research Cosmetic Approach for Healthy and Damaged Hair
Hair can't be reliably repaired once damaged; prevention and proper product use are key to maintaining hair health.
research Investigation of Hair Shaft in Seborrheic Dermatitis Using Atomic Force Microscopy
Hair from people with seborrheic dermatitis is thicker scaled, more damaged, and thinner than healthy hair, and atomic force microscopy can help monitor the condition.
research Characterization of Human Ovarian Teratoma Hair Using AFM, FT-IR, and Raman Spectroscopy
Teratoma hair is similar to scalp hair but has a rougher surface and lower adhesive force.
research Heat-Damaged Evaluation of Virgin Hair
Heat damages hair, with Asian hair losing more protein than Caucasian hair.
research Charge Density Alterations in Human Hair Fibers: An Investigation Using Electrostatic Force Microscopy
The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.
research Whole Exome Sequencing in Alopecia Areata Identifies Rare Variants in KRT82
Rare changes in the KRT82 gene are linked to a higher risk of Alopecia Areata.
research Investigation of Human Hair Fibers Using Lateral Force Microscopy
Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.
research Investigation of Aging Effects in Human Hair Using Atomic Force Microscopy
Aging makes hair thinner and rougher, with less clear edges.
research WNT10A Mutation Causes Ectodermal Dysplasia by Impairing Progenitor Cell Proliferation and KLF4-Mediated Differentiation
A WNT10A gene mutation leads to ectodermal dysplasia by disrupting cell growth and differentiation.
research Tribological Properties Between Taut Hair Fibers in Wet Conditions: A New Shampoo Formulation for Eliminating Stick-Slip Friction
Shampoo B, which uses water-soluble silicone, is better at detangling hair in wet conditions due to its two-layer conditioning film.
research Science and Technology of Hair Fibers
The document concludes that understanding hair's composition and the effects of treatments can lead to better hair care products.
