From Johns Hopkins Medicine - "Platelet-rich plasma (PRP) injections are gaining popularity for a variety of conditions, from sports injuries to hair loss. The treatment uses a patient's own blood cells to accelerate healing in a specific area." The healthcare professional takes a small blood sample and puts it in a centrifuge and once separated, the plasma is injected into the affected area. As with anything, do your research on trusted websites, discuss with your doctor and consider the benefits vs the risks. It worked for me. Insurance didn't cover and it was about $3k for three sessions (spaced out by a month each time) for me. I live in Colorado.

I just googled it and it’s Platelet Rich Plasma.
