research Monitoring of Wool Stretching Process Using Polarized Second Harmonic Generation
Stretching wool changes its structure and improves fiber alignment.
research A method to measure oil penetration into hair and correlation to tensile strength
Type 3 hair oil strengthens hair more than coconut oil.
research Cyclic combing of untreated and bleached human hair: Analysis of the time‐dependent breakage of hair through recording the formation of fibre fragments
Friction causes hair breakage during combing, and fragment count predicts hair strength.
research Mechanical Properties of Epoxy-Based Composite Reinforced with Kenaf, Grewia Serrulatta, Human Hair Fibers
research Regulation of hard α-keratin mechanics via control of intermediate filament hydration: matrix squeeze revisited
Hard α-keratins stay stiff in water because the surrounding matrix keeps them dehydrated and strong.
research Cuticle damage and the tensile properties of human hair
Cuticle damage doesn't affect hair's tensile strength; the cortex is responsible for it.
