research Analyzing the laser-light reflection from human hair fibers. I. Light components underlying the goniophotometric curves and fiber cuticle angles.
The research found a way to measure hair surface changes by analyzing how light reflects off of it, and determined hair cuticle angles vary by hair length and color.
research Sphingolipids of the Murine Hair
Murine hair has specific types of ceramides and glucosylceramides but lacks acylceramides.
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 Bidirectional binding property of high glycine–tyrosine keratin-associated protein contributes to the mechanical strength and shape of hair
High glycine–tyrosine keratin-associated proteins help make hair strong and maintain its shape.
research Seasonal Variability in Transcript Expression of Type I and Type II Keratins in Wool Follicles of Lustrous Fleece-Producing Magra Sheep
Higher keratin protein levels are important for the wool's shine in Magra sheep.
research A hair abnormality in Abyssinian cats
Abyssinian cats can have a hair abnormality that makes their coat look rough and dull.
research The effect of treatments on the shear modulus of human hair measured by the single fiber torsion pendulum.

research Monilethrix: an ultrastructural study
Monilethrix hair issues are due to problems in the hair's internodes.
research Characterization of the proteins of guinea-pig hair and hair-follicle tissue
Guinea-pig hair and follicle proteins are mostly similar, but follicles have more group 2 proteins and fewer group 3 and 4 proteins.
research Potential use of human hair shaft keratin peptide signatures to distinguish gender and ethnicity
Keratin peptides in hair might help identify gender and ethnicity.
research Peer Review #1 of "Human hair shaft proteomic profiling: individual differences, site specificity and cuticle analysis (v0.1)"
