Heterochromia of the scalp hair: a result of pigmentary mosaicism?
Five patients who presented stable bands of hair of a different color with respect to the surrounding hair are reported. In 4 patients this was an isolated finding. One patient also had diffuse linear skin hypopigmentation and other abnormalities. We hypothesize that these 5 cases represent a distinct type of hair heterochromia, possibly because of somatic mosaicism for genes affecting pigmentation.
