research Photoageing of Hair Fiber and Photoprotection
Sunlight damages hair, causing cuticle loss, protein changes, and discoloration.
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 Experimental Investigations on Hair Fibers as Diffusion Bridges and Opiates as Solutes in Solution
Hair can absorb and transfer opiates when soaked in water, with damaged hair absorbing more.
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 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 Analyzing the laser‐light reflection from human hair fibers. II. Deriving a measure of hair luster
The conclusion is that a new method to measure hair shine was confirmed to match people's visual assessments.
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 Marangoni effect in the water wetting of surfactant coated human hair fibers
The study found that the Marangoni effect causes the uneven wetting of surfactant-coated hair due to the surfactant moving into the water.
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 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 Studies of light scattering from ethnic hair fibers
Different hair types from various ethnic groups affect hair shine due to characteristics like thickness and shape.
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 The Binding of Small Molecules and Polymers to Keratin and Their Effects on the Physicochemical and Surface Properties of Hair Fibers
Certain small molecules and polymers can change hair's physical properties and how it feels by affecting the bonds within the hair.
research High-throughput phenotyping methods for quantifying hair fiber morphology
Hair fiber shape and curvature are not significantly linked when ancestry is considered.
