보문 : 두피 모발의 굵기에 따른 큐티클층의 미세구조적 특성

We investigated the ultrastructure of the cuticle layer of hairs of different thickness from the scalp of the same woman by scanning electron microscopy. Hair thickness varied from 30 μm to 110 μm. Scanning electron microscopy showed that the cuticle layer of fine hairs about 40 μm in diameter consisted of only 4 cuticular cells, whereas the cuticle layer of thick hairs about 110 μm in diameter consisted of 10 cuticular cells. The diameter of cuticular cells of both hair types was 0.3~0.5 μm. We conclude that coarse hairs have a thick cuticle layer consisting of more cuticular cells, whereas fine hairs have a thin cuticle layer consisting of fewer cuticular cells.
