Hi. This is my first post.
Been following the prp treatment with enthusiasm and I want to applaud the doctors who are willing to try this experimental procedure.
Searching on the internet I found that there are a few patents on this concept filed by David R Knighton.
Don't know if I'm allowed to post links to these patents so I won't, but you can find them on google.
Though I don't know whether the procedure described in these patents is similar to the procedure performed today, what troubles me is that these patents are from the early nineties (one was filed on Jan 10 1989)
If it was known 20 years ago that prp may promote hair growth and it could actually produce significant results, shouldn't it have become common practice by today?
