Trichoscopy does not allow visualization of the most specific feature of trichothiodystrophy: the “tiger tail” bands. Thus, trichothiodystrophy cannot be diagnosed based on trichoscopy. Nonspecific findings are a nonhomogenous structure of hair shafts, resembling grains of sand, and a very slightly wavy contour. Trichoschisis may be observed, but distinction between trichoschisis and trichoclasis is not possible by trichoscopy.
