Microstructure of Curved Human Hair

摘要：

The microstructure of curved human hair was investigated, using fluorescence light microscopy (FLM), transmission electron microscopy (TEM) and electron tomography. FLM and TEM observations revealed that human hair cortex contained four classifiable cell types, two of which were present in much greater abundance than the remaining two types. These cell types were annularly and evenly distributed in straight hair, while the cell types were bilaterally distributed in curved hair. One dominant cell type was predominantly observed in the convex side of the curved fiber shape, and the other was in the concave side. Electron tomography confirmed that the dominant cell type in the convex side contained discrete macrofibrils composed of helically arranged intermediate filaments, while the dominant cell type in the concave side contained larger fused macrofibrils composed of intermediate filament arrangements varying from helical to hexagonal arrays approximately parallel to the longitudinal fiber axis. These findings concur with the current hypothesis of hair curvature formation and behavior.
