Circle hairs (CHs) represent a body hair growth disorder which is characterized by asymptomatic presence of hairs in typical circular or spiraliform arrangement. It is not associated with follicular or inflammatory abnormalities. CHs are rarely reported, probably underestimated, as medical consultation for CH only is rare in practice. It needs to be differentiated from rolled hairs, which is a relatively common disorder of hair growth associated with follicular hyperkeratosis and keratin plugging. Trichoscopy is a noninvasive technique to confirm the diagnosis without biopsy. We present a 20-year-old female who presented with CHs over bilateral upper and lower limbs involving extensors.
环形毛发（CHs）是一种体毛生长紊乱疾病，其特征是毛发呈典型的圆形或螺旋状排列且无明显症状。它与毛囊或炎症异常无关。CHs很少被报道，可能存在低估情况，因为在实际临床中仅因CH进行医学咨询的情况很少见。它需要与卷曲毛发相鉴别，卷曲毛发是一种相对常见的毛发生长紊乱疾病，与毛囊角化过度和角质堵塞有关。皮肤镜检查是一种无需活检就能确诊的非侵入性技术。我们报告了一名20岁女性，其双侧上下肢伸侧出现了环形毛发。
