Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain itchy and burning feeling in hair, face,upper back after hair dye along with flaking, itching of the scalp seems to be due to severe
anaphylactic reaction caused by the components present in the dye..
I would suggest you to
consult a Dermatologist or an Allergist and get evaluated and a thorough clinical evaluation and investigations can help in diagnosis and treatment can be done accordingly..
You can be advised oral antiallergics and
steroids like
Allegra or Levocetrizine, another round of steroids, topical application of steroid ointment, shampoo containing coaltar and Ktoconazole as there might be
fungal infection also and cool compresses..
Injectable steroids can be given for faster relief..
Hope this information helps..
Thanks and regards.
