Abstract

Trichonodosis is characterized by knotted hair on the distal portion of the hair shaft. This may be spontaneous or secondary to mechanical factors like vigorous scratching or combing the hair. We report a case of spontaneous trichonodosis with abnormal scalp and body hair.

Keywords: Abnormal hair growth; kinky hair; trichonodosis.
