hi. I have read your question and understand your concern. red itchy scaly rashes behind the ear can be because of seborrheic dermatitis. seborrheic dermatitis is a type of eczema. patients suffering from this disorder may also have itchy flaky scalp, itching over eyebrows, eyelashes, upper back. all the symptoms may not be present in every person. If such a patient visited my clinic, my prescription would be triatop shampoo thrice weekly candid- b cream twice daily tab levosiz once daily I suggest you see your dermatologist and confirm your Diagnosis and then get a prescription. hope this helps. for any further questions please get back to us. thanks.
