First you need to check hair fall is due to baldness or some other reason. If it is male pattern baldness wich is hereditary, you can go for hair transplantation. There is no other proper treatment for that. First consult a good trichologist. Then he can decide the cource of treatment.
The only 2 medicine that is proved to be helpfull are
1. Monoxidil (Mintop) -> topical use
2. Finipecia which is a hormon inhibitor which will temporarily inhibts effect of your male hormon.
So doing a hair transplantion and using these two medicine will solve your problem. Hair transplant may cost rs 20-30/hair. You may need 1000 - 2000 transplants
