Int J Trichology. 2011 Jan;3(1):46-56. doi: 10.4103/0974-7753.82124.

Abstract

Light microscopy of the hair forms an important bedside clinical tool for the diagnosis of various disorders affecting the hair. Hair abnormalities can be seen in the primary diseases affecting the hair or as a secondary involvement of hair in diseases affecting the scalp. Hair abnormalities also form a part of various genodermatoses and syndromes. In this review, we have briefly highlighted the light microscopic appearance of various infectious and non-infectious conditions affecting the hair.

Keywords: Hair shaft anomalies; infections; infestations; light microscopy; trichogram.
