research Uncombable-hair Syndrome
Four children had unmanageable pale blond hair due to uncombable-hair syndrome.
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 FEMALE CADAVER IN THE HAN TOMB NO. 1 X-RAY DIFFRACTION STUDIES ON TWO KINDS OF FIBROUS PROTEIN
The protein structures in the hair and tendon were preserved, but their molecular arrangements changed.
research Structural interspecies variability of mammals' hairs
Mammal hairs have different internal structures.
research Structure of intermediate filament assembly in hair deduced from hydration studies using small-angle neutron scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
research Two siblings with uncombable hair syndrome: A new pathogenic variant
Two siblings have a rare hair condition caused by a new genetic variant.
research Organization of microfibrils in keratin fibers studied by X-ray scattering
The study improved understanding of keratin fiber structure by showing consistent microfibril diameter but varying distances and electron density profiles.
research Trichothiodystrophy hair shafts display distinct ultrastructural features
Trichothiodystrophy hair is structurally abnormal with protein and organization issues.
research Acquired progressive kinking of hair affecting the scalp and eyelashes in an adult woman
A woman developed rare, unexplained curly hair on her scalp and eyelashes.
research Accumulations of Ca/P in the core of hairs from Taklamakan desert mummies

research Protein chains in hair and epidermal keratin IF: Structural features and spatial arrangements
research In-Situ Tensile Testing of Hair Fibers in An Environmental Scanning Electron Microscope (ESEM)
Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.
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.
