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

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.
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 Tactile Innervation Densities Across the Whole Body
The skin has about 230,000 touch-sensitive nerve fibers, with high concentrations in the hands and face.
research Abstracts: Reduction-Induced Surface Modification of Human Hair
Chemical treatments change hair surface properties, making it more hydrophilic and able to bind conditioners.
research Physical Characteristics of Anatolian Native Goat Down-Hair Fibers in Comparison with Cashmere Fiber
Anatolian native goat down-hair is similar to cashmere and can be used for high-quality textiles.
research Artificial Hair Implantation for Hair Restoration
Artificial hair implants can quickly improve looks and life quality, but they have risks like infection and early fiber loss, so more research is needed to confirm their safety and effectiveness.
research Changes of Curvature with Regain of Set Wool and Hair Fibers
Merino wool fibers change shape with moisture, while human hair shape stays the same.
