Hair transplant is a better alternative.

Greetings. Yes Prp definitely works, however the extent to which it does varies in different patients. However, I have had a positive feedback about therapy from most of my patients and there are studies in literature to prove it's efficacy in hair growth. But make sure you get it done by a qualified dermatologist. Hope this solves your doubt. Further queries may be sent on follow up messaging. Warm regards.
