30-60 / 739 results 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 Chapter 4: Cytomechanics of Hair
Hair's strength and flexibility come from its protein structure and molecular interactions.
research Evolution of Trichocyte Keratins
Hair keratins evolved from ancient proteins, diversifying through gene changes, crucial for forming claws and later hair in mammals.
research Chemical Modification of Keratin Fibers Using 2-Iminothiorane Hydrochloride
2-iminothiorane hydrochloride improves hair waving permanence without 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 Homo- and Heteropolymer Self-Assembly of Recombinant Trichocytic Keratins
Recombinant keratins can form useful structures for medical applications, overcoming natural keratin limitations.
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 Copper and Calcium Uptake in Colored Hair
Hair coloring increases copper and calcium uptake, damaging hair and reducing shine.
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 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 Secondary Structure Estimation and Properties Analysis of Stretched Asian and Caucasian Hair
Stretching damages Caucasian hair's structure more easily than Asian hair.
research Structural Optimization of Pep7, a Small Peptide Extracted from Epimorphin, for Effective Induction of Hair Follicle Anagen
Modified pep7, named EPM peptide, effectively promotes hair growth at low concentrations and works well with minoxidil.
research Cleave But Not Leave: Astrotactin Proteins in Development and Disease
Astrotactin proteins are important for brain and skin development and are linked to several neurodevelopmental disorders.
research Evaluation of Cysteic Acid in Bleached Hair Using Infrared Spectroscopy
Bleaching hair increases cysteic acid levels in a predictable way.
research A Detailed Mapping of the Readily Accessible Disulfide Bonds in the Cortex of Wool Fibers
Researchers found that the most reachable bonds in wool fibers are near the ends of certain proteins, which help stabilize the fiber's structure.
research Keratin
Understanding how keratin structures in hair are arranged and interact is key for creating methods to extract and purify them.
research Expression of Novel Keratin-Associated Protein 5 Genes in the Cuticle Layer of Human Hair Follicles
The study found nine new hair protein genes in human hair follicles.
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 Water-Soluble Polymers in Hair Care
Alkaline hair relaxers damage hair, but cationic and non-ionic polymers can help reduce this damage.
