A Guide to Platelet-Rich Plasma (PRP) Therapy for Hair Loss
What is PRP Therapy? Platelet-Rich Plasma (PRP) Therapy is a non-surgical, regenerative treatment designed to stimulate natural hair growth using the healing power of your own body. A small amount of your blood is drawn and processed in a centrifuge to concentrate the platelets. This enriched plasma is then carefully injected into targeted areas of the scalp. The growth factors released by the platelets help improve blood flow to hair follicles, reinforce hair root strength, extend the active growth phase of the hair cycle, and support overall scalp health by reducing inflammation.
How many sessions are needed, and when can I expect to see results? A typical PRP treatment course begins with 3 to 4 sessions spaced approximately 4 to 6 weeks apart. To maintain results, follow-up sessions are usually recommended every 4 to 6 months, depending on the individual’s response and the extent of hair loss. Most patients begin to notice reduced hair shedding and visible improvements in thickness and density within 3 to 6 months. Some may experience earlier signs of progress.
Is PRP Therapy safe, and are there any side effects? Yes, PRP Therapy is widely regarded as safe since it uses your own blood, significantly reducing the risk of allergic reactions or infections. Side effects are generally mild and short-lived, typically limited to slight tenderness, swelling, or redness at the injection sites. These effects usually resolve within 24 hours. When administered by an experienced practitioner, complications are rare.
