Woolly Hair



In woolly hair, trichoscopy demonstrates hair shafts with waves at very short intervals, giving the hair a “crawling snake” appearance. Hair shaft thickness appears uneven because of the twists that are typical for this condition. Entangled and broken hairs may be present. Trichoscopy is not decisive for diagnosis.
