Greetings. Vitiligo is a disease that needs to be understood in detail. An attempt to find the underlying cause has to be made. Traditionally it is believed to be a difficult disease to conquer but with increasing knowledge it is easier than before. The first target is to halt the progression and then to refill the lost colour. It is sometimes associated with other diseases, one of them is thyroid. Medications and exact details is possible when you a Dermatologist in person.
