Answer

Canities

Graying of hair occurs with various conditions as well as naturally with aging.

Prurigo (prurigo nodularis)

Prurigo nodularis appears as a heaped keratotic inflammatory nodule on the extensor surfaces of the arms, legs, and trunk. Lesions are pruritic, and patients find themselves incessantly picking them with their fingers and nails.
