PRP stands for Platelet-Rich Plasma and is considered an effective nonsurgical treatment option for hair loss; in many cases, the therapy has proved successful, and clients have seen positive results. Patients no longer need to go under the knife to have thick hair, thanks to this novel treatment. Studies have shown that PRP, in addition to preventing hair loss, helps strengthen and regrow hair. Hence, PRP is often a common treatment prescribed by doctors as a post-care option after a hair transplant to further strengthen the newly-transplanted hair.
