Abstract
Morphological and ultrastructural characteristics of human hair medulla was investigated with scanning electron microscopy and transmission electron microscopy. The medulla is located in the central position of hair shaft and appear greatly variable forms which discontinuous shape arranged from hair root to apical portion according to longitudinal axis. The thickness of medulla from a single hair presented as very variable in size. The diameter of cross section of human hair medulla measured as $21{\mu}m$ and longitudinal section showed $27{\mu}m$. It grows up to 1/3 from 1/4 in diameter of human hair shaft. It appears emptied hole during separating of macrofibrils in the keratinocyte. The empty space measured $6.5{\mu}m$ in diameter as maximum size and it was filled with air.
