Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.
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 Deep Hair Phenomics: Implications in Endocrinology, Development, and Aging
A new tool can analyze hair to detect changes due to hormones, genetics, and aging.
research A New Approach to the Bending Properties of Hair Fibers
The new test shows how hair treatments affect hair's bending stiffness by swinging a pendulum through hair fibers.
research Tactile Innervation Densities Across the Whole Body
Young adults have about 230,000 tactile nerve fibers, decreasing 5-8% per decade with age.
research Evaluation of Hair Surface Structure and Morphology of Patients with Lichen Planopilaris by Atomic Force Microscopy
AFM can help diagnose lichen planopilaris by identifying specific hair structure changes.

Cosmetic residues on individual hairs can be identified and differentiated using ATR FT-IR microspectroscopy.
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 Age, Lifestyle, and Self-Perceptions of Hair: Is There an Association with Hair Diameter and Tensile Properties?
Older age and certain lifestyles are linked to thinner, weaker hair, while how you see your hair relates to its thickness.
research Interactions Between Crossed Hair Fibers at the Nanoscale
Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.
research Hair Styling: Technology and Formulations
Hair styling products and tools help improve hair's look and manageability but can damage hair if used incorrectly.
research Notes from the Editor Emeritus
The author believes that in hair restoration, creating an illusion of coverage is more important than perfection, and managing expectations and improving average results should be prioritized over promising unrealistic outcomes.
research Improving Stable Isotopic Interpretations Made From Human Hair Through Reduction of Growth Cycle Error
The conclusion is that recognizing hair growth cycles can improve the precision of dietary and health assessments from hair analysis.
research Characterization of Hair Lipid Images by Argon Sputter Etching-Scanning Electron Microscopy
Hair texture changes with age due to varying levels of lipids.
research Rare Case of Recurrent Hair in the Floor of the Mouth
Hair grew in a man's mouth due to a rare condition called heterotopia.
research Investigation of the Damage on the Outermost Hair Surface Using ToF-SIMS and XPS
Bleaching hair causes significant damage by breaking down proteins and fatty acids.
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 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 Internal Structure Changes in Bleached Black Human Hair Resulting from Chemical Treatments: A Raman Spectroscopic Investigation
Chemical treatments on bleached black hair change its internal structure by breaking and reforming bonds, and treatments with hydrolyzed eggwhite protein help repair it.
research Three Streams for the Mechanism of Hair Graying
Hair graying may be caused by stem cell depletion from stress or melanocyte damage.
