Cuticle patterns of 5 subjects living in different countries have been studied under a scanning electron microscope. Hair cuticle pattern in different individuals can be complex, simple, or mixed type. The most incident is the complex type of hair cuticle pattern (75-80%), while the simple type is much more rare (15-20%) and the mixed type still more rare (2-5%). Variation statistical analysis helped differentiate hairs from aborigines of some countries of Asia, Africa, Latin America, and East Europe by the number of cuticle pattern lines. High efficiency of scanning electron microscopy in studies of hair cuticle patterns is shown.
