I tried having one PRP injection, and I was skeptical, because I read that five injections are needed. The doctor told me however that even if I have one injection, I should notice something, and if it does nothing I don't need to try again.
It sounded okay to me! If it has a good effect, I will probably write a report here. I don't expect much, but it is a very non-invasive and cheap procedure. It seems good to combine it with other procedures, not just as a stand-alone procedure.
