Thank you for asking the question.
seborrheic dermatitis and dandruff cause the itchy scalp in most of the cases. these conditions have high recurrent rate and are difficult to treat,
the doctor uses different options, if one doesn’t work, he moves another. there are other conditions that may cause such itchy scalp, which may need different medications. Therefore, the proper examination is needed, see a qualified dermatologist for a professional opinion. if one thing doesn’t work go and tell the doctor your previous medication didn’t work, he will choose the next option, even if that doesn’t work go again he will move to the 3rd stop.
Regards.
