research Can hair be protected from oxidative damage during and after bleaching
L-arginine, hydrolysed keratin, and cystine-silanol copolymer can help protect hair from damage during and after bleaching.
research Technique for Processing and Routing Staining of Hair Samples for Histological Study
A new method effectively stains hair samples for study without losing hair sections.
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 Enzymatic phosphorylation of hair keratin enhances fast adsorption of cationic moieties
Enzymatic phosphorylation of hair keratin improves the effectiveness of hair products with cationic ingredients.
research The Potential Teeth Bleaching and Halitosis Prevention Effects of Pediococcus inopinatus THK-30, a Kimchi-Derived Lactic Acid Bacterium: In Vitro Study
A kimchi-derived bacterium could help whiten teeth and prevent bad breath.
research Impact of oxidative hair coloring and bleaching on hair fiber properties
Bleaching damages hair the most, while dyes improve combability but still cause protein loss.
research Effects of Skin Lightening Cream Agents – Hydroquinone and Kojic Acid, on the Skin of Adult Female Experimental Rats
Hydroquinone may harm skin, while kojic acid and aloe vera could reduce its negative effects.
research Amino Acid Content of Damaged Human Hair
High temperatures and certain chemicals can significantly change the amino acid content in human hair.
research Individual Human Hair Keratin Rapidly Extracted Through the Advanced Oxidation Process and Their Hemostatic and Wound Healing Evaluations
The new method extracts keratin from hair faster and better, and the resulting product improves blood clotting and wound healing, with potential for personalized treatments.
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 physical and chemical disruption of human hair after bleaching – studies by transmission electron microscopy and redox proteomics
Bleaching hair causes severe structural and chemical damage, including protein loss and oxidation.
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 science of color: How chemical dyeing processes transform hair structure
Oxidative dyes damage hair more than semi-permanent dyes, but new technologies help protect hair while coloring.
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 #3665 Glyoxylic acid induce crystalline nephropathy and hair-straightening products: a case report
Hair-straightening products with glyoxylic acid can cause kidney damage.
research Polyphenolization:Hair Browning by Phenolic Adhesion,Ambient Oxygen, and Transition Metals
A new hair dye method uses polyphenols and oxidation to create a long-lasting brown color on gray hair.
research Action of Nucleophilic Reagents on Hair Keratin
Nucleophilic reagents break down hair keratin, forming more lanthionine and lysinoalanine than in wool.
research Biomechanics of chemically treated hair for continuous 1D strands
NaOH treatment improves hair strength and suitability for textiles.
research A Keratin Fiber Sheath
Hair fibers may have a unique, non-protein sheath not previously identified.
research Investigation of pH effect on cationic solute binding to keratin and partition to hair
Solute binding to hair keratin is mainly driven by hydrophobic interactions and changes with pH.
research A 20-year retrospective clinicopathologic study on melanoma in Singapore
Bleach baths with 0.005% hypochlorite help manage atopic dermatitis by affecting skin cells and reducing itchiness.
research The science of color: How chemical dyeing processes transform hair structure
Oxidative dyes damage hair more than semi-permanent dyes, but new technologies help protect hair while coloring.
research Some histological and biochemical evaluation on commercial hair dyes
Commercial hair dyes can harm the skin and liver.
research Dyeing behaviours of amino heterocyclic compounds as blue oxidative hair dye precursors applied to keratin fibres
1,2,3,4-tetrahydroquinoline compounds are great for stable, pure blue hair dye.
research Enzymatic synthesis of biosafe hematoxylin dyes on hair: enhanced post-dyeing hair health and boosting color fastness
This eco-friendly hair dye method improves hair health and color durability.
research Understanding the Effect on Hair Fibers of Coloring and Bleaching Formulations Using High Pressure Differential Scanning Calorimetry (HPDSC)
Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.
research Key locations of oxidative damage in human hair keratins after heat and ultraviolet light exposure
Heat and UV exposure damage hair structure by altering keratins.
research A stain for plucked anagen hairs
A new staining method helps tell growing from resting hairs to diagnose hair loss.
research DSC-investigations of alpha-keratins and the specific effects of chemical treatments on human hair
Chemical treatments weaken hair's thermal stability and structure.
