Selenium sulfide-associated scalp discoloration

Synopsis
Discoloration of the scalp and hair from selenium sulfide shampoo has been rarely reported. It typically presents as orange, red, or red-brown discoloration and has been seen in children and adults. The pathomechanism is thought to be deposition of selenium sulfide powder, which is orange, on the skin. The discolored areas can be removed with an alcohol swab, solidifying the diagnosis. An orange-brown discoloration of nails and lighter-colored hair (blond or gray) has also been reported. One case of green hair discoloration can be found in the literature as well.
It is possible that the compound may also cause a shift to telogen and therefore hair thinning or loss, particularly with intense and prolonged exposure, and it may increase oiliness of the scalp by increasing sebaceous gland secretion and/or size. It may impact the color or longevity of some hair dyes.
