Trichoscopy of Hair Shaft: White Nodules

Trichoscopy is a tool each time more used in the diagnosis of hair disorders. We describe two cases of white nodules on the hair shaft, their findings under microscopy and trichoscopy. The diagnosis of these hair shaft abnormalities is usually done by microscopy or electron microscopy of the affected hair; but trichoscopy was an easy, rapid, comfortable and useful method in the differential diagnosis of these conditions.
