Update on my PRP treatments: My hairline - where the treatments were applied is thick So are my sideburns. Hair on my sideburns stretches to below my jaw. Other than the one stubborn area on the left t side, the hairline thinning has disappeared. I'll have my last (#6) PRP treatment, in the series of six, next week. As I mentioned before, the anesthetic injections hurt like the dickens - but I would do PRP again. I was considering doing an additional 6 months of treatment, however my doctor wants me to take a 3-6 month break. During the 3-6 month break I'll continue applying emu oil and folligen.
