PRP (platelet-rich plasma) therapy for hair loss is a three-step medical treatment in which a person’s blood is drawn, processed, and then injected into the scalp.
Some in the medical community think that PRP injections trigger natural hair growth and maintain it by increasing blood supply to the hair follicle and increasing the thickness of the hair shaft. Sometimes this approach is combined with other hair loss procedures or medications.
PRP for hair loss side effects
Because PRP therapy involves injecting your own blood into your scalp, you aren’t at risk for getting a communicable disease.
Still, any therapy that involves injections always carries a risk of side effects such as:
- injury to blood vessels or nerves
- calcification at the injection points
- scar tissue
There’s also the chance that you could have a negative reaction to the anesthetic used in the therapy. If you decide to pursue PRP therapy for hair loss, let your doctor know in advance about your tolerance to anesthetics.
