How long does platelet rich plasma treatment last?

PRP can work well for many patients, and I typically prescribe a regimen of 3 initial treatment session spaced one month apart followed by maintenance injections every 6 to 12 months. This seems to work well for most of my patients.
I always recommend discussing your concerns with a fellowship-trained hair restoration surgeon.
All the best,

A series of 3 PRP treatments are recommended and can be combined with low level light therapy (Theradome).  After the initial series, maintenance will be required.  Most patients will do a quarterly or bi annual program.
