Circle hair refers to a specific hair growth disorder characterized by asymptomatic hairs that grow in a perfect circular or spiral pattern, without any underlying follicular abnormalities or inflammation. This condition was first identified by Adatto in 1963.
Key Characteristics of Circle Hair:
- Appearance: Hairs are arranged in a circular or spiral shape.
- Symptoms: Generally, the condition is asymptomatic (doesn't cause any symptoms like pain, itching, or discomfort).
- Associated Conditions: Not usually associated with other skin or scalp conditions.
- Cause: The exact cause is not fully understood.
- Diagnosis: Diagnosed primarily based on visual examination.
- Treatment: Typically, no treatment is required as it's asymptomatic.
Essentially, circle hair is a peculiar but generally harmless condition where hair strands grow in a circular formation on the scalp.
