The surface and transverse sections of human hair using scanning (SEM) and transmission electron microscopy (TEM) were studied. The cellular structures such as hair cortex and cuticle and such sublamellar cuticle structure as A-layer, the exo-, endocuticle and cell-membrane complexes were identified. It was shown that physical and chemical characteristics of the cuticle determinate its function as a molecular sieve and chemical barrier against the action of various factors.

Keywords: hair, ultrastructure, cuticle, cortex, pathology
