Overview

Pili torti is a rare hair condition characterized by fragile hair. In pili torti hair has a flattened shaft with clusters of narrow twists at irregular intervals.[1] Some cases are genetic while others are acquired. In the inherited form, symptoms tend to be present from early childhood. It can occur alone or in association with ectodermal dysplasias, Menke disease, Bjornstand syndrome, or Bazex syndrome. Acquired cases of pili torti may be associated with anorexia nervosa, malnutrition, oral retinoid treatment, or inflammatory scalp conditions (e.g., cutaneous lupus erythematousus).[1] Click here to visit DermAtlas and view an image of a child with pili torti.
