Hi, You seem right. You probsbly have vitiligo on scalp. Vitiligo is an autoimmune disease. Exact cause is not known. The prognosis is totally unpredictable. In some pstients it heal by itself without treatment. In others, it might increase in numbers and size...and spread to other areas. In few,it remain stable. For patients like you,I would like to advise line of treatment as follow.. - Methoxsalen 25 mg tablet daily in morning - Levamisole 50 mg at night - Apply methoxsalen solution in morning and at noon. Expose to sun after application. - tarolimus lotion may be applied at night This treatment may be advised to continue for few months few years or tillgood result is achieved. I hope this would benefit i your treatment. You cosult dermatologist and have perfect treatment. Thanks. Dr. Ilyad Patel MD
