Hi, thanks for your query.
It seems you have been diagnosed androgenic alopecia
.It is genetically determined in which androgen sensitivity of the hair follicle increases leading to short and slow growing phase.
The treatment you have been given is apt for androgenic alopecia. It will definitely help in reduction of hair fall
and promote hair growth but this would not be justified if I say that you will have hair like before.
Secondly it depends on the stage of alopecia, results are better in early stages.
You need to take treatment for long time and it may take 4-6 months to see visible results. So a lot of patience from your side is required.
Hope this solves your query.
