Suggest Remedy For Itching And Black Scar Due To Allergy To Dye

Respected Dr, My name is Abdul Nazir age of 45, I was using hair dye (Black Gold - Black Henna of M/s. Ishar Dass Amir Chand, Email: YYYY@YYYY ) for coloring my hair for last 18 months and i did not have any problem. Recently i have noticed itching after applying the above dye. When i applied the same on my beard, very soon all my beard became white and even mustache, which made my appearance difficult to recognize for my friends also. Now i am suffering without getting a proper dye which does not have allergy or any proper treatment to cure the allergy. Now some black scars appeared on my forehead due to the continued allergy. As I approached a Doctor (Allergy and Dermatology) , it was advised not to use any type of Dye to color my hair. He prescribed Medrol (4 mg) 2 tablets each morning 3 continuous days with 4 days interval and Fexodine tablets 1 each at night. Still i am not getting complete cure from itching and black scars. Can you advise me where i get a proper treatment to cure my allergy and use any hair dye for my hair, beard and mustache.

Your valuable advise is requested.

Sincerely yours.
