circle hairs trichoscopy follicular hyperkeratosis keratin plugging

TLDR Circle hairs are harmless, spiral-shaped body hairs that don't need medical treatment.

Circle hairs (CHs) were described as a body hair growth disorder characterized by the asymptomatic presence of hairs in circular or spiraliform arrangements, without follicular or inflammatory abnormalities. The condition was rarely reported and likely underestimated, as individuals seldom sought medical consultation solely for CHs. It was important to differentiate CHs from rolled hairs, which were associated with follicular hyperkeratosis and keratin plugging. Trichoscopy was highlighted as a noninvasive method to confirm CH diagnosis without the need for a biopsy. The document presented a case of a 20-year-old female with CHs on her bilateral upper and lower limbs.
