research An ultrastructural study on corkscrew hairs and cigarette‐ash‐shaped hairs observed by dermoscopy of tinea capitis
Corkscrew and cigarette-ash-shaped hairs in tinea capitis are caused by internal hair degradation and external resistance.
research Progenitor‐cell‐enriched micrografts as a novel option for the management of androgenetic alopecia
Micrografts promote hair growth in androgenetic alopecia treatment.
research Three‐dimensional imaging and analysis of the surface of hair fibres using scanning electron microscopy
The new 3D imaging method accurately measures hair surface details quickly.
research Heat‐damaged evaluation of virgin hair
Heat damages hair, with Asian hair losing more protein than Caucasian hair.
research Charge density alterations in human hair fibers: an investigation using electrostatic force microscopy
The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.
research The structural implications of water hardness metal uptake by human hair
Human hair absorbs calcium and magnesium from tap water, affecting its structure and styling properties.
research Copper and calcium uptake in colored hair
Hair coloring increases copper and calcium uptake, damaging hair and reducing shine.
research Lipid loses 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 Hair Mechanical Properties Depending On Age And Origin
Hair properties vary with age and ethnic origin.
research Understanding breakage in curly hair
Curly hair breaks due to mechanical damage and environmental factors, not chemical makeup, and needs ongoing care to prevent breakage.
research Pattern of expression of c-Myc, Max and Bin1 in human anagen hair follicles
c-Myc, Max, and Bin1 help hair follicle cells mature and die.
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 Elucidating penetration pathways into the hair fiber using novel microscopic techniques.
The conclusion is that substances can penetrate hair fibers through multiple pathways, including both the cell membrane complex and the non-keratinous parts.
research Copper in Green Hair: A Quantitative Investigation by Electron Probe X-Ray Microanalysis
Green hair has high copper levels due to contaminated water and damaged hair cuticles.
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 Localization of S100A2, S100A4, S100A6, S100A7, and S100P in the human hair follicle.
Different S100 proteins have specific roles in various parts of the hair follicle.
research Torsional method for evaluating hair damage and performance of hair care ingredients
The torsional method effectively evaluates hair damage and the performance of hair care ingredients.
research Why Mammal Body Hair Is an Evolutionary Enigma
The evolution of mammal body hair remains a mystery.
research Ultrastructural localization of hair keratins, high sulfur keratin-associated proteins and sulfhydryl oxidase in the human hair
Hair proteins change location and structure as hair cells mature.
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 A systematic review on the lipid composition of human hair
Lipids are crucial for healthy hair, protecting it from damage and breakage.
research Distribution Analysis of Triglyceride Having Repair Effect on Damaged Human Hair by TOF-SIMS
Hydrogenated palm oil repairs and conditions damaged hair by preventing swelling.
research Preparation of Water Soluble Wool Keratin and Its Application for Human Hair
