Greetings. Sometimes a single shampoo need not be enough. You need to be evaluated by a qualified dermatologist near you / in your city and treated with shampoos / lotions / oral medications if necessary. The common causes of itchy scalp could be dandruff, sebopsoriasis, psoriasis, folliculitis, etc . further queries may be sent on follow up messaging. Warm regards.
