Hi Kashif...you will have this heriditary baldness problem. but right now you are having itchy scalp that is because of dendruff in chief. so first you should get off with this problem which can really damage your hair badly and make it really thin and weak. which ultimately leads to baldness. clean your hair regularly with some antidendruff shampoo. you can try Head & shoulder, clinic all clear antidendruff shampoo( also can use KZ kind of medicated shampoo containing ketoconazole). or u can also try some ayurvedic product like Trichup shampoo and hair oil of antidendruff category. for baldness (heridietry) with minoxidil(5%) and finasteride (combination) solution like Mintop or any other combination available in the market. but before opting for this consult some dermatlogist around and let him decide. because efficacy of this product on a long run is not that much convincing.
