Before one gets these PRP injections, a few steps have to be followed. However, there are different ways in which PRP injections can be injected. For example, sometimes before injection, a numbing lidocaine solution is smeared on the scalp. For this solution to be applied, you may have to come early to the hospital. At times PRT is mixed with an anesthetic to reduce any distress. Doctors occasionally apply PRP in the course of surgery. Getting ready for PRP injections also include following the recommendations from your surgeon before the surgery. Understand more what is PRP before using it.
