Have any of you friends heard of or tried PRP injections? While not FDA approved yet, it is a series of injections into the scalp that uses part of your own blood cells. It would be a great alternative to meds, minoxidil. I am curious about it. My research indicates a maintenance of twice yearly shots and is not surgery with no bad side effects. it's been used to heal sports injuries. Wouldn't it be a god send for us?
