Types of Vitiligo

Vitiligo is categorized into two types:

Segmental Vitiligo or Unilateral Vitiligo

It tends to affect areas of skin that are associated with dorsal roots from the spine and is most often unilateral. Often seen on a leg, face or arm, about half of the affected lose some hair colour, such as on the head, an eyelash or an eyebrow. It generally has an early onset, often advances for a year or so and then stops.

Non-segmental Vitiligo

It could be focal or generalized. Focal Vitiligo can be abortive type of Segmental or Generalized Vitiligo. Generalized Vitiligo or vitiligo vulgaris has bilateral origin, such as both hands and knees. Usually begins on the hands, fingertips, wrists, around the eyes or mouth, or on the feet. Individuals experience rapid loss of skin colour in the beginning, which then stops after a while, eventually leading to repeated colour loss. This start-and-stop cycle usually continues all through a person's lifetime. Colour loss tends to propagate, covering larger vicinity, thus increasing visibility. Acrofacial and Mucosal vitiligo are type of generalized vitiligo.
