• There are three classifications of vitiligo: nonsegmental, segmental, and mixed type. Segmental is considered the most refractory.
  • Vitiligo is associated with autoimmune comorbidities, with thyroid disease being the most prevalent comorbidity.
  • Treatment response in vitiligo is best on the face and neck and least effective on the hands and feet.
  • The goal of vitiligo treatment is 75% improvement.
  • The presence of a hair follicle is needed for vitiligo to repigment. Patches with majority white hairs and glabrous skin (lips, wrists, fingertips) do not repigment.
