Poliosis found later in life is acquired and is sometimes a side effect of a medical condition, such as Waardeburg's syndrome, tuberous sclerosis, thyroid disease, skin cancer and a variety of other genetic or autoimmune diseases and disorders.

Herpes zoster, otherwise known as shingles, can cause the white patch in the hair either temporary or permanently. Patients who have undergone radiation or chemotherapy often develop the white patching hair due to the treatment destroying pigment producing cells.
Anyone who develops poliosis is recommended to see a doctor right away. The doctor will run tests and conduct a medical history to find out if there is cause for concern.
