research What Factors Play a Role in Unhealthy Hair?
Environmental, chemical, mechanical, and personal health factors can all damage hair and contribute to hair loss or changes in hair quality.
research Study on Modification of Rabbit Hair Fibers with L-Cysteine
L-cysteine and ultrasound successfully improved rabbit hair fibers for industrial use.
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 Cosmetics, Hair, And Nails
Hair and nails are skin parts that develop early and serve protective and functional roles.
research Plants Used in Cosmetics
Natural products in cosmetics are beneficial for skin and hair care with low toxicity.
research Effect of Disulfide Bonds in Human Hair Fibers on the Melting Behavior of Their Crystalline Structure
Changing disulfide bonds in human hair affects its melting behavior and thermal stability.
research Effect of Disulfide Bonds in Human Hair Fibers on the Melting Behavior of Their Crystalline Structure
Disulfide bonds affect the melting behavior of hair's crystalline structure, but hair retains some stability even after these bonds are broken.
research Solubility of Structurally Complicated Materials: Hair
Hair is hard to dissolve because of its complex proteins, but certain solvents that break specific bonds and hydrate can do it.
research Copper and Calcium Uptake in Colored Hair
Hair coloring increases copper and calcium uptake, damaging hair and reducing shine.
research Disulfide Cross-Linked Network Structure of Intermediate Filament and Matrix in Hair and Wool Cortices
Hair and wool strength is affected by the number and type of bonds in their protein structures, with hair having more protein aggregates than wool.
research Action of Thioglycolic Acid and L-Cysteine on Disulfide Cross-Links in Hair Fibers During Permanent Waving Treatment
Thioglycolic acid and L-cysteine change hair structure differently during perms, affecting hair strength and curling efficiency.
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 Analysis of Heterogeneous Reaction Between Reducing Agents and Keratin Fibers Using Raman Spectroscopy and Microspectrophotometry
The study found that thioglycolic acid breaks down hair bonds more consistently than l-cysteine, which is less damaging to hair.
research Reduction Mechanism of L-Cysteine on Keratin Fibers Using Microspectrophotometry and Raman Spectroscopy
L-cysteine slows down the breaking of bonds in hair due to electrostatic interactions.
research Preparation and Characterization of Soluble Wool Keratin for Human Hair Care
CMADK reduces hair damage from bleaching and permanent waving.
research Effects of Ultraviolet Radiation on the Soluble Proteins of Human Hair
UV radiation increases protein loss from hair and reduces hair protein quality.
research Reconnection Of Cysteine In Reduced Hair With Alkylene Dimaleates Via Thiol-Michael Click Chemistry
A new method using 1,4-n-butylene dimaleate effectively repairs and strengthens damaged hair.
research Keratin
Understanding how keratin structures in hair are arranged and interact is key for creating methods to extract and purify them.
research Bleached Hair as a Standard Template to Evaluate the Performance of Commercial Hair Repair Products
K18® and Olaplex® both effectively repair bleached hair, improving its strength, smoothness, and overall health.
research Electron Microscope Studies of Hair and Wool
Hair and wool have complex microscopic structures with microfibrils and varying cystine content.
research Crystalline Cataract and Uncombable Hair Syndrome in a 7-Year-Old Girl
The study found no common cause for a girl's crystalline cataract and uncombable hair, suggesting their co-occurrence might be coincidental.
research Biology of Human Hair: Know Your Hair to Control It
Understanding hair biology is key to developing better treatments for hair and scalp issues.
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 Methods of Hair Straightening: Temporary and Permanent Techniques
Hair straightening changes hair structure and can cause damage if done wrong, but improvements in the methods are expected to continue.
research Repair of Damaged Hair Protein Fiber by Jointly Using Transglutaminase and Keratin
Using an enzyme and keratin treatment can significantly repair and strengthen damaged hair.
research Hair Straightening: Techniques, Chemicals, and Evolution
Hair straightening methods have advanced to improve effectiveness and reduce damage, but still rely on heat and chemicals.
research The Impact of AP Collagen Peptides on Hair Shaft Elasticity and Gloss: A Comprehensive Analysis
AP collagen peptides improve hair elasticity and gloss.
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 Effect of Protein Hair Straightener on Hair Shaft by Scanning Electron Microscopy
Protein hair straighteners damage the hair more than hair dyes.
