"Uncombable hair" is the denomination applied to a new abnormality of the hair, being characterized by its arranged in bundles disposed in different directions and which are irreductible on combing. It may have a familial trait and starts at the age of 3 months onwards. It appears in children of both sexes, whose hair becomes dry, tightly curled, shiny, lighter and impossible to comb. There are no accompanying abnormalities in the development. Neither have any biological changes been registered. The clinical and ultrastructural aspects of 10 cases of children affected with "uncombable hair" are presented. At the scanning electron microscope we have observed longitudinally disposed canalicular formations on the cuticular surface of 50 p. 100 of hair taken from each patient. The canal is, in some zones, more excavated than in others, occasionaly has an irregular outline and sometimes is uniformly located nearly along the whole length of the hair. The transversal section shows triangular aspects, kidney-shaped or completely irregular. We agree with Dupré to use the term pili canaliculi for the defect shown by these patients.
“难梳理头发”是用于描述一种新发毛发异常的名称，其特征为头发成束状且方向各异，梳理时无法理顺。它可能具有家族性特征，从3个月大开始出现。男女儿童均可发病，患病儿童的头发变得干燥、紧密卷曲、有光泽、颜色变浅且无法梳理。发育过程中无伴随异常。也未发现任何生物学变化。本文介绍了10例患有“难梳理头发”儿童的临床和超微结构特征。在扫描电子显微镜下，我们观察到从每位患者采集的毛发中，50%的毛小皮表面有纵向排列的小管状结构。这些小管在某些区域比其他区域更深，偶尔轮廓不规则，有时几乎沿毛发全长均匀分布。横断面显示为三角形、肾形或完全不规则形。我们同意杜普雷的观点，将这些患者所表现出的缺陷称为毛发小管。
