Hair Loss Treatment Concerns. Need advice from an expert.

[Pides]

Through the research I have made I found that I will have better results if before the hair transplant (I am planning to have a FUE hair transplant next summer) I start a therapy with minoxidil, finasteride and PRP. This therapy it is suggested to be continued after the hair transplant, for ever as I understand. My main concerns are: will I have the same results without PRP, and which combination between the three (minoxidil, finasteride and PRP) will be most effective before and after the transplant?
