Why aren't more US doctors using PRF platelet rich fibrin rather than offering just the regular PRP platelet rich protein?

Question

The slower spinner device is relatively reasonably priced & there are impressive before & after pictures showing results with a dr using this amazing source. He also explains in detail the better benefits of PRF compared to PRP. I think the slower spinner machine might be called eclips- but I don't recall. Spinning at a slower spin, with the current PRP machines do not work. This small sized slower spinner model only yields the wonderful PRF results needed!

The majority of the studies and data have utilized PRP. Metanalysis shows that PRP is effective. In my opinion, PRF is best utilized with an intradermal injection. Timing is important in this situation and makes the process more complicated. I believe that subdermal depo injection provides better spread of the platelets and is less painful. Furthermore, PRF contains more red cells and white cells which are not helpful in hair rejuvenation.Jeff Rapaport MD FAADRealself Verified All-star

The value of PRP may be in the microneedling alone, not the actual PRP used.  See the reference below which discusses the guest speaker's opinion at the recently ISHRS meeting
