Do not worry my dear, no doubt there is a relationship between vitiligo
and thyroid disorder
but after taking thyroxine
daily for along time your vitiligo will be lessen. For now you should start applying demovate ointment twice a day for 10 days then do not apply for 10 days before applying again for the same period.do not forget to apply sunscreen of SPF 60 before going outside in the sun.
