Hair growth may involve a pulling force from the outer root sheath.
research Acquired morphological changes of mammalian hair scales
Mammalian hair scales change from smooth to wavy due to friction.
research Intrinsic curvature in wool fibres is determined by the relative length of orthocortical and paracortical cells
Wool fibre curvature is due to longer orthocortical cells compared to paracortical cells.
