FAQWill it spread?

Vitiligo activity may vary considerably from person to person.

In a good number of patients the disease goes on for 3-4 years and then it settles down, with one or two stubborn patches and the clearance of the others. 

There are also patients where the disease shows periods of stability and then suddenly starts increasing. Yet, a small number of patients go from having dark skin to having totally depigmented skin and hair in a period of months.

The natural course of vitiligo is truly unpredictable but usually progressive.
