PRP therapy is a non-surgical treatment option that uses the patient’s own blood to stimulate hair growth. The patient’s blood is drawn and then centrifuged to extract platelet-rich plasma, which is injected into the scalp. PRP therapy is believed to promote hair growth by increasing blood flow to the hair follicles and promoting the growth of new hair cells. The treatment is typically done in multiple sessions and can cause some side effects, such as swelling, redness, and discomfort.
