March 2014 in “Biological reviews/Biological reviews of the Cambridge Philosophical Society” This study introduces the multiple papillary centres model, offering a new explanation for hair twisting by combining known hair morphology features with differential growth rates caused by dermal papillae.

March 2018 in “Journal of Experimental Biology” This study found that hair curvature in merino wool is influenced by differences in cell type length rather than the proportions of orthocortical and paracortical cells.

December 2021 in “Frontiers in cell and developmental biology” This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.
9 citations

July 2018 in “Acta biomaterialia” This study reports a good correlation between the curvature of human eyelashes and the displacement of the neutral axis, influenced by the non-uniform thickness of the outer cuticle layer.
