Acquired trichorrhexis nodosa
Keywords:
Trichorrhexis nodosa, hair disease, hair shaftAbstract
Acquired trichorrhexis nodosa is a rarely reported hair disorder, but it is likely to be a common disorder. It is characterized by keratin alterations of the hair cuticle shaft which produces increased hair fragility to chemical or physical injuries and generates some clinical features as frayed, brittle or dry hair, with shortened growth and whitish nodules on the hair shaft, which help in the suspected diagnosis. Light microscopy and trichoscopy show typical images of incomplete fracture of the hair shaft that look like two brushes facing each other. The treatment is to avoid these traumas, and use of hair conditioners and vitamins, because there is no specific treatment.
