How Can Hair Fall With Itching And Dandruff Be Treated?

Hi, I am 21 years old guy and I am experiencing some hairfall since past two months. Morning after bath i see 5 10 hair on my hands while setting them. Even when i move my hands randomly through my hair i see on or two hair strands on my hand. Also i feel my hair have become thin. I have itching also along with this hairfall and also dandruff. I don t use any shampoo for hairwash. I wash my hair with the regular soap which i use for bathing. Doy aloe vera is the soap I m using. I ll like to know how to stop the hairfall and regain the thickness of my hair. My father too has a bald patch on the center of the head and i am also expereincing major hairfall in that area. It can be heridatory. Also which shampoo should i use. And i have heard about tugain. Will it help? Thank you.
