The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.
research Analysis of DNA in hair fibers.
Small amounts of DNA can be found in the hair shaft, especially near the root, but it decreases with hair treatments and washing.

research Formation of surface membranes in developing mammalian hair fibres
Mature hair surfaces are formed by keratinized cells with developed layers, not just modified plasma membranes.
research Fine structure of marsupial hairs, with emphasis on trichohyalin and the structure of the inner root sheath
Marsupial hair structure and keratin distribution are similar to placental mammals.
research An Electron Microscopy Study of Keratin Degradation by the Fungus Microsporum gypseum in vitro
Microsporum gypseum fungus breaks down keratin in hair by digesting it enzymatically, starting with less keratinized parts.
research Hair Keratin Associated Proteins: Characterization of a Second High Sulfur KAP Gene Domain on Human Chromosome 2111In fond memory of Dr Peter Steinert.
A second domain of high sulfur KAP genes on chromosome 21q23 is crucial for hair structure.
research Fine structure and immunocytochemistry of monotreme hairs, with emphasis on the inner root sheath and trichohyalin‐based cornification during hair evolution
Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.
research Morphology and ultrastructure of antler velvet hair and body hair from red deer (Cervus elaphus)
Antler velvet hair and body hair of red deer have different structures that help with protection and insulation.
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 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 The kinetics of moisture sorption by hair
Hair absorbs moisture differently based on its structure and treatment, with changes occurring at 30% humidity.
research Observation of different HHK groups with SEM
Different human hair keratin types have unique structures that affect how they dissolve and can be used to create self-tendons.
