Doctor recommended 10 sessions of PRP and I’m 22 years old.

The doctor recommended 10 sessions of PRP at $500/session.   I would guess you might purchase a good used car for that $$ amount. So if you were shopping for a car, you would research it, right? Doubt that you will stop your hair loss with PRP and reversing it is another story! Some doctors are just not honorable. I can tell you that I would doubt that you would get much value from this PRP package.
