Does Lidocaine reduce effectiveness of PRP?

Hello and thank you for your question. In my experience Lidocaine does not reduce the effectiveness of PRP, if it did I would assume a doctor would not use it. I hope this helps.

The few studies suggesting that lidocaine interferes with platelet function demonstrate a very minimal impact on PRP therapy—and because topical analgesics like lidocaine are administered in such small amounts during injection, this effect would be considered insignificant. At our clinic, nearly all patients opt to use lidocaine during PRP therapy for hair loss, and we see exceptional results with no correlation to the use of analgesics. Additionally, most PRP practitioners offer, and even default, to using lidocaine, so you shouldn’t need to apply it before your appointment.
