research Evaluation of Cysteic Acid in Bleached Hair Using Infrared Spectroscopy
Bleaching hair increases cysteic acid levels in a predictable way.
research Influence of Oxidative and Reductive Treatment on Human Hair: Analysis of Hair Damage
Chemical treatments and daily stresses damage hair, especially the cuticle layer.
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 Investigating the Relationship Between the Hair Fiber Proteome and Hair Quality
Hair quality is genetically determined and linked to its composition and strength.
research Hair Loss Management
Eat a balanced diet for healthy hair; only use supplements if you have a proven nutrient deficiency.
research Cosmetics, Hair, And Nails
Hair and nails are skin parts that develop early and serve protective and functional roles.
research Change in Surface Chemistry of the Cuticle of Human Hair by Chemical and Photochemical Oxidation
Oxidation changes human hair by breaking down fats and forming new acidic groups, affecting how it interacts with conditioners and cosmetics.
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 Copper and Calcium Uptake in Colored Hair
Hair coloring increases copper and calcium uptake, damaging hair and reducing shine.
research Comparison of Damage to Human Hair Fibers Caused by Monoethanolamine- and Ammonia-Based Hair Colorants
Monoethanolamine-based hair colorants can cause more damage to hair than ammonia-based ones.
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 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 Vibrational Raman and IR Data on Brown Hair Subjected to Bleaching
Bleaching hair changes its structure and weakens it, which is important for understanding hair damage and creating treatments.
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 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 Annurca Apple Polyphenols Protect Murine Hair Follicles from Taxane-Induced Dystrophy and Redirect Polyunsaturated Fatty Acid Metabolism Toward β-Oxidation
Annurca apple extract may protect mouse hair from damage by chemotherapy and could help treat hair loss without promoting cancer growth.
research Distribution of Glycolipid and Unsaturated Fatty Acids in Human Hair
Human hair has more unsaturated fats inside than on the surface, and certain lipids may help bind the outer and inner layers together.
research Exploring the Effects of Wetting and Free Fatty Acid Deposition on a Hair Fiber Surface Model Incorporating Keratin Associated Protein 5-1
Water and fatty acids affect hair's surface differently based on hair damage, and models can help understand hair-cosmetic interactions.
research Annurca Apple Polyphenols Ignite Keratin Production in Hair Follicles by Inhibiting the Pentose Phosphate Pathway and Amino Acid Oxidation
Annurca apple extract promotes hair growth by changing hair follicle metabolism to boost keratin production.
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 Chemical Reactions in Curing Treatment for Permanent Hair Straightening Using Thioglycolic and Dithioglycolic Acids
Using both TGA and DTDG in hair straightening reduces hair damage compared to using TGA alone.
