After getting traumatic vitiligo, if the surrounding skin has the presence of irritants such as sunlight exposure or reoccurring trauma, then it is possible to cause the lesions to spread.

If you are diagnosed with traumatic vitiligo, you need to follow the doctor’s instructions to prevent the further spread of vitiligo.
