Hi. Greetings. You'll need to be examined to rule out any skin lesions associated with itching. Did you apply any new hair care product or gel ?? You can take a anti histamine tablet like cetrizine for temporary relief from itching. But it's better you come down for a consultation or meet a qualified dermatologist near you so that the problem can be identified and treated. Hope this helps. Let me know if u need any further assistance in this regard.
