30 / 1000+ results 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 Analysis of Structural Changes in Permanent Waved Human Hair Using Raman Spectroscopy
Permanent waving weakens hair by altering its protein structure.
research Measuring Changes in Chemistry, Composition, and Molecular Structure Within Hair Fibers by Infrared and Raman Spectroscopic Imaging
Infrared and Raman imaging can non-destructively analyze hair structure and help diagnose hair conditions.
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 Copper and Calcium Uptake in Colored Hair
Hair coloring increases copper and calcium uptake, damaging hair and reducing shine.
research Characterization of Hair Lipid and Protein Dynamics Using EPR Spectroscopy and Treatment Effects
Hair treatments and dehydration affect hair's lipid and protein behavior, influencing its flexibility and appearance.
research Structural Investigation on Damaged Hair Keratin Treated with α,β-Unsaturated Michael Acceptors Used as Repairing Agents
Treatments improved hair surface and scale structure but didn't increase certain bonds in the hair cortex.
research A Highly Resistant Structure Between Cuticle and Cortex of Human Hair
A tough membrane between the outer and inner layers of human hair protects it from damage.
research SEM/SDD-EDS: An Analytical Tool to Identify Waterborne Micro Minerals Pickup in Human Scalp Hair Cuticle Due to Water Quality
Water quality affects mineral content in hair, and coconut oil can protect against damage.
research Characterization of the Promoter Regions of Two Sheep Keratin-Associated Protein Genes for Hair Cortex-Specific Expression
The KRTAP11-1 gene promoter is crucial for specific expression in sheep wool cortex.
research Scanning Electron Microscopes/Silicon Drift Detector-Energy Dispersive Spectroscopy: An Analytical Tool to Identify Waterborne Microminerals Pickup in Human Scalp Hair Cuticle Due to Water Quality

The enzymatic method can effectively identify chemical treatments on hair.
research Lipid Losses and Barrier Function Modifications of the Brown-to-White Hair Transition
White hair has less lipid content and absorbs water differently than brown hair.
research Penetration and Distribution in Human Skin Focusing on the Hair Follicle
Targeting drugs to hair follicles can treat skin conditions, but reaching deep follicle areas is hard and needs more research.
research Multidimensional Profiling of Human Body Hairs Using Qualitative and Semi-Quantitative Approaches with SR-XRF, ATR-FTIR, DSC, and SEM-EDX
Body hairs can be used in forensic science and toxicology like scalp hair.
research Discrete Nanoscale Distribution of Hair Lipids Fails to Provide Humidity Resistance
Hair lipids do not protect against humidity.
