30 / 1000+ resultsresearch The in vitro Assembly of Hair Follicle Keratins: Comparison of Cortex and Companion Layer Keratins
Different conditions affect how hair proteins assemble, and certain mutations can change their structure.
research Investigation by Imaging Mass Spectrometry of Biomarker Candidates for Aging in the Hair Cortex
Certain molecules in hair change with age and could be used for cosmetic treatments.
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 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 hKAP1.6 and hKAP1.7, Two Novel Human High Sulfur Keratin-Associated Proteins are Expressed in the Hair Follicle Cortex
Two new proteins, hKAP1.6 and hKAP1.7, are found in the hair follicle cortex.
research Cortical cell types and intermediate filament arrangements correlate with fiber curvature in Japanese human hair
Hair curvature in Japanese people is linked to specific cell types and filament arrangements in the hair cortex.
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 Local structure of human hair spatially resolved by sub-micron X-ray beam
Human hair has a new region with ordered filaments and the cuticle contains β-keratin sheets.
research Keratin formation in the hair follicle
Keratin fibrils in hair form and stop growing at specific points in the follicle.
research Heat‐damaged evaluation of virgin hair
Heat damages hair, with Asian hair losing more protein than Caucasian hair.
research Measuring Finasteride Efficacy
Finasteride's effectiveness measured by observing hair cortex changes using a cheap and easy method.
research Proteomic tools for the investigation of human hair structural proteins and evidence of weakness sites on hair keratin coil segments
Hair proteins have weak spots in their α-helical segments.
research Disorders of Hair Pigmentation
Hair color is determined by melanin and can be affected by genetic conditions like albinism.
research Acidic and basic hair/nail ("hard") keratins: their colocalization in upper cortical and cuticle cells of the human hair follicle and their relationship to "soft" keratins.
Hair and nail cells share similar proteins, indicating a common differentiation pathway.
research Types of Hair Dye and Their Mechanisms of Action
Hair dyes vary in how long they last and how deeply they penetrate hair.
research Organization and Expression of Hair Follicle Genes.
Hair growth is controlled by specific gene clusters and proteins, and cysteine affects hair gene expression in sheep.
research Healthy Hair: What Is it?
Healthy hair is shiny, smooth, and has clean ends.
research A discourse on human hair fibers and reflections on the conservation of drug molecules
Hair analysis for drugs needs a better understanding of how drugs enter hair, considering factors like hair structure and pigmentation.
research Known and Unknown Features of Hair Cuticle Structure: A Brief Review
The hair cuticle is made of tough proteins that protect the hair, but more research is needed to fully understand its structure.
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 Discrete Nanoscale Distribution of Hair Lipids Fails to Provide Humidity Resistance
Hair lipids do not protect against humidity.
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 Human hair keratin network and curvature
Curly hair shape is due to uneven growth patterns in the hair follicle.
research Compartmentation of Mitochondrial and Oxidative Metabolism in Growing Hair Follicles: A Ring of Fire
Growing hair follicles have high mitochondrial activity and ROS in specific regions, aiding hair formation.
research Qualitative investigation of fresh human scalp hair with full-field optical coherence tomography
Melanin density affects hair color, and this method can help in cosmetic assessments and diagnosing hair diseases.
research Physical Properties of Human Hair. 1. Evaluation of Bending Stress by Measuring the Major and the Minor Axis of Human Hair.
The cuticle significantly contributes to hair stiffness, making up about 60% of the total bending stress.
research Strain and Strain Recovery of Human Hair from the Nano- to the Macroscale
Human hair can almost fully recover its structure within about 1,000 minutes after being stretched.
research Cosmetic Approach for Healthy and Damaged Hair
Cosmetic procedures can harm hair, but damage can be minimized with knowledge and care; however, once hair is damaged, it cannot be reliably repaired.
research Ultrastructural Characteristics of Neonate Scalp Hair
Neonate scalp hair is thinner, lacks a medulla, and has smaller follicles compared to adult hair.
