More research is being released every day regarding the effectiveness of PRP for hair loss, including some medical hair loss problems that otherwise don't have a good solution. PRP is still a relatively new treatment for male pattern baldness, and more evidence is coming out all the time to support its use. While PRP is not going to generate new hair follicles where none exist, I do consider it to be a good option for patients who do not want a hair transplantation procedure, or would like additional non-surgical treatments to support a transplant. I consider it another tool in my toolbox for treatment of hair loss, just like minoxidil, finasteride, etc. All the best,
