The reasons for vitiligo formation are still unknown, but there is some relation to genetics. If your parents or ancestors have had vitiligo, there is a high chance of you being affected. Both men and women can be victims of vitiligo, and the condition is more prominent in those with dark skin. There’s no specific age as to when vitiligo might appear, but the appearance is stronger at an older age. Those with a family history are at a greater risk.
It’s hard to tell if this condition will spread or not, but there is a chance that it can. Those affected by a specific type of vitiligo called “localized vitiligo” don’t have to worry about the spread. Additionally, undergoing certain treatments can help minimize the appearance of patches.
