Hair microdiffraction patterns in linear intensity grey scale. (a) Pattern of the outer zone of horse hair in perpendicular geometry, 7 µm under the surface (hair axis is vertical). The keratin is moderately ordered α-type. (b) Pattern of the horse-hair core in perpendicular geometry (∼50 µm below the surface). Strong typical features of hard α-keratin are visible (hair axis is vertical). (c) Diffraction signals from lipid granules in the outer zone of human hair in parallel geometry (3 µm under the surface). The diffraction rings indicate a random orientation of the stacks. (d) Diffraction signals from lipid granules in the outer zone of horse hair in parallel geometry (3 µm under the surface). The diffraction arcs indicate a preferential orientation parallel to the surface.
