SETTING: An outpatient dermatology clinic in an urban area; patients diagnosed in a 2-year period were included in the study. RESULTS: Halo scalp ring is most commonly a temporary, nonscarring alopecia that occurs in patients born to primigravidas. CONCLUSIONS: Halo scalp ring is a distinctive form of alopecia attributed to caput succedaneum. It is underreported and generally has a good prognosis. However, scarring may occur.
