Growing Hair from Body Fluid Injections to the Scalp?

I heard of a technique where your own bodily fluid is injected into the male pattern balding spot and is supposed to grow hair. Can you tell me what you know about this treatment? Is it for real, is it permanent, is it for the frontal part of the scalp etc.?

I don’t know of injecting body fluid (???) in your scalp to grow hair… but I do know some clinics offer platelet rich plasma (PRP) into the scalp in hopes it will provide faster healing after a hair transplant. Some dentists use it for faster healing after a dental procedure. I asked a few dentist friends, one of which is a professor at UCSF, and she believes PRP is controversial even in the dental field.

In the end, this method has never really been proven to grow hair on a bald scalp. If anyone can find a well controlled study for hair growth from PRP, please let me know. Some doctors charge hundreds or thousands of dollars for PRP, but I remain a bit skeptical. The patients we’ve viewed in the office haven’t had the results their doctors promised.
