Vivek aged 38 is allergic to hair color. He has tried several brands patch test on hand but after a days application the test area becomes like a burn boil with water inside. There is lot of itching and it continues for 10 to 15 days until some antibiotic is taken to suppress the same. My question is do we have any medication or anti allergic available so that hair color may be applied without allergy or else he should drop this idea of hair color application forever. Please suggest.
