You need to be evaluated to know the reason for your hair fall. Dandruff, Androgenetic Alopecia , alopecia Areata etc all can cause hair fall and the treatment for each varies. There is no blanket treatment (one shampoo or one lotion for all ) for hair fall or even in the treatment of the skin.

My sincere suggestion is that you visit an allopathic dermatologist near you. Before you choose your dermatologist read this http://www.skinmatra.com/single-post/2016/07/03/Skin-Troubles-Here-is-WHAT-NOT-TO-DO
Do not self medicate and refrain from trying home remedies.
