research Effect of equilibrium pH on the structure and properties of bleach‐damaged human hair fibers
Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.
research Morphological analysis of polymers on hair fibers by SEM and AFM
Polyquaternium 7® builds up on hair, improving its look and feel, and AFM is good for measuring these changes.
research Quantifying Polymer Deposition on Hair Fibers by Microfluorometry
Microfluorometry effectively measures how much polymer coats and penetrates hair, useful for evaluating hair products.
research The cell membrane complex: Three related but different cellular cohesion components of mammalian hair fibers
The cell membrane complex in mammalian hair has three distinct types with different structures and chemical properties.
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 The human type I keratin gene family: Characterization of new hair follicle specific members and evaluation of the chromosome 17q21.2 gene domain
The study identified and characterized new keratin genes linked to hair follicles and epithelial tissues.
research Wetting behavior of human hair fibers
Human hair's ability to get wet is complex and can change with treatments, damage, and environment.
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 Molecular modeling of hair keratin/peptide complex: Using MM‐PBSA calculations to describe experimental binding results
Electrostatic interactions mainly stabilize the binding of peptides to hair keratin.
research Induction of Hair Keratins Expression by an Annurca Apple-Based Nutraceutical Formulation in Human Follicular Cells
An apple-based supplement was found to stimulate hair protein production, which may help with hair growth.
research How different is human hair? A critical appraisal of the reported differences in global hair fibre characteristics and properties towards defining a more relevant framework for hair type classification
Human hair varies widely and should be classified by curl type rather than race.
research Fractal geometry and topology abstracted from hair fibers
Hair fibers have fractal patterns with properties related to the golden mean, which may affect their functionality.
research Single hair fiber assessment techniques to discriminate between mineral oil and coconut oil effect on hair physical properties
Coconut oil makes hair stronger and more flexible than mineral oil.
research Hair today, gone tomorrow: the degradation and conservation of archaeological hair fibers
Acidic sandy clay damages archaeological hair the most, while dry conditions preserve but make it brittle; silicone oil can help keep the hair flexible.
research Self-Assembly of Solubilized Human Hair Keratins
Human hair keratins can form stable nanofiber networks that might help in tissue regeneration.
research Systems Approach to Human Hair Fibers: Interdependence Between Physical, Mechanical, Biochemical and Geometric Properties of Natural Healthy Hair
Hair properties are interconnected; a comprehensive, cross-disciplinary approach is essential for understanding hair behavior.
research A 6-Month, Prospective, Multi-arm Study for the Efficacy of Standardized Nutraceuticals to Improve Hair Fiber Thickness and Strength
Nutrafol® nutraceuticals improve hair thickness and strength.
research Stability of opiates in hair fibers after exposure to cosmetic treatment
Cosmetic treatments like bleaching and perming can greatly reduce opiate levels in hair, possibly leading to false-negative drug tests.
research Investigation of human hair fibers using lateral force microscopy
Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.
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 The adsorption behavior of cationic surfactant onto human hair fibers
A certain surfactant sticks to human hair, making it change from water-repelling to water-attracting, which could help in hair conditioning.
research Exogen involves gradual release of the hair club fibre in the vibrissa follicle model
Hair sheds gradually from the follicle, with readiness to shed indicated by less attachment material.
research The Interaction of Hair Fibers with Alkali Bromide Solutions
Hair absorbs alkali bromide salts and water, affecting its structure, with absorption decreasing at higher temperatures.
research Tribological Properties between Taut Hair Fibers in Wet Conditions: A New Shampoo Formulation for Eliminating Stick‐Slip Friction
Shampoo B, which uses water-soluble silicone, is better at detangling hair in wet conditions due to its two-layer conditioning film.
research Examining polyquaternium polymers deposition on human excised hair fibers
Certain polymers can stick to hair and increase volume, working best at a pH of 7 to 9.
research Automatic Artificial Hair Implant: Safety and Efficacy in Androgenetic Alopecia. A Prospective Study with a Highly Biocompatible Fiber
Implant safely and effectively treats hair loss.
research Cryogelation of human hair keratins
Human hair keratins can be turned into useful 3D biomedical scaffolds through a freeze-thaw process.
research A reciprocal lattice approach to assessing the luster of hair fibers, based on scattering by periodically deformed cylinders
A new method helps understand hair shine and various products improve hair care.
research Pigmented Hair-Thickening Fibers: A Camouflage Technique for Alopecia in Patients with Epidermolysis Bullosa
Colored hair-thickening fibers can help hide hair loss in some people with Epidermolysis Bullosa but may cause scalp irritation.
