30 / 412 resultsresearch 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 Internal structure changes in bleached black human hair resulting from chemical treatments: A Raman spectroscopic investigation
Chemical treatments on bleached black hair change its internal structure by breaking and reforming bonds, and treatments with hydrolyzed eggwhite protein help repair it.
research Distribution and Localization of Hydrophobic and Ionic Chemical Groups at the Surface of Bleached Human Hair Fibers
Bleaching hair removes its protective top layer and exposes more hydrophilic groups, changing its chemical surface and affecting how it interacts with products.
research On Pathways for Small Molecules Into and Out of Human Hair Fibers
Dye enters hair at the edges of cuticle cells and penetrates more from water than alcohol-based solutions.
research Protein disulphide 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 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 The structural implications of water hardness metal uptake by human hair
Human hair absorbs calcium and magnesium from tap water, affecting its structure and styling properties.
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 Simultaneous RP-HPLC-DAD determination of dansyl amino acids in chemically treated human hair
A new method accurately measures amino acids in treated hair, showing bleaching reduces amino acids while protein treatments increase them.
research Application of XANES profiles to X-ray spectromicroscopy for biomedical specimens: Part II. Mapping oxidation state of cysteine in human hair
Perming and bleaching damage hair differently, with bleached hair having more cysteic acid in the cuticle.
research Raman spectroscopic analysis of L‐phenylalanine and hydrolyzed eggwhite protein penetration into keratin fibers
L-phenylalanine and hydrolyzed eggwhite protein deeply penetrate human hair.
research Diffusion behavior of poly(ethylene imine) into keratin fibers using microspectrophotometry
PEI diffuses into hair at a constant rate, and urea speeds up this process.
research Evaluation of Cysteic Acid in Bleached Hair Using Infrared Spectroscopy
Bleaching hair increases cysteic acid levels in a predictable way.
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 Effect of equilibrium pH on the structure and properties of bleach‐damaged human hair fibers
Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.
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 Interactions between Crossed Hair Fibers at the Nanoscale
Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.
research Learning from hair moisture sorption and hysteresis
Hair moisture behavior helps tell apart different chemical treatments and reveals insights into hair structure.
research Suitability of hair type for dermatophytes perforation and differential diagnosis of T. mentagrophytes from T. verrucosum
Human black hair is best for distinguishing between T. mentagrophytes and T. verrucosum.
research Keratin‐based particles for protection and restoration of hair properties
Keratin-based particles safely improve hair strength, smoothness, and heat protection.
research The kinetics of moisture sorption by hair
Hair absorbs moisture differently based on its structure and treatment, with changes occurring at 30% humidity.
research Significant damage of the skin and hair following hair bleaching
Hair bleaching causes significant damage to hair and skin.
research New method of dyeing keratin fibers using poly(ethylene imine) and its coloring mechanism
A new method using poly(ethylene imine) improves hair dyeing at lower temperatures with better color retention.
research The adsorption behavior of cationic surfactant onto human hair fibers
A certain surfactant sticks to human hair, making it change from water-repelling to water-attracting, which could help in hair conditioning.
research Human hair growth ex vivo is correlated with in vivo hair growth: selective categorization of hair follicles for more reliable hair follicle organ culture
Choosing hair follicles at the same growth stage leads to more consistent hair growth experiments.
research Damage limitation: comparing the impact of polymers on bleached hair, when applied within or as post-bleach treatments
Polymers help reduce damage and improve bleached hair when used during or after bleaching.
research <b>Hair keratin film as a substitute device for human hair </b>
Keratin film can effectively replace human hair for testing hair damage.
