Circle hairs (CH) represent a body hair growth disorder characterized by asymptomatic presence of hairs with typical circular or spiraliform arrangement, not associated with follicular or inflammatory abnormalities. Although this condition is rarely reported, it is probably underestimated, as a medical consultation for CH only is rare in practice. Trichoscopic and histopathological findings of CH have never been reported and this article will present and discuss six cases along with literature review.
环形毛发（CH）是一种体毛生长障碍，其特征是出现无症状的毛发，呈典型的圆形或螺旋状排列，与毛囊或炎症异常无关。尽管这种情况很少被报道，但可能被低估了，因为在实际中仅因CH进行医学咨询的情况很少见。CH的皮肤镜和组织病理学表现从未被报道过，本文将介绍并讨论6例病例，并进行文献综述。
