Platelet-rich plasma (PRP) therapy is gaining popularity for treating hair loss and other conditions, but many patients ask the same question: how long does PRP last? At Kopelman Hair, we guide patients through personalized treatments, and knowing what to expect regarding results and longevity is essential.

Understanding PRP and Its Function

This regenerative treatment involves using a patient’s own blood to stimulate healing and regeneration. The process starts with drawing a small amount of blood, which is then spun in a centrifuge to isolate the plasma. 

This substance is rich in growth factors that boost cellular repair and improve tissue health. The goal is to concentrate platelets to accelerate the body’s natural healing process.The platelet rich plasma procedure is straightforward and minimally invasive.

Once prepared, the platelet rich plasma injection is administered into the affected area to activate healing. It is commonly used for hair restoration, skin rejuvenation, and joint discomfort. In some cases, local anesthetics may be used to minimize any injection-related discomfort.

Application in Hair Restoration

This therapy is widely used to help patients with thinning or early-stage hair loss. It encourages the growth phase of hair follicles and helps repair damaged tissue in the scalp. At Kopelman Hair, we customize each PRP treatment to match individual patterns and goals, ensuring safe and effective outcomes.

For those curious about real-life transformations, we recommend reviewing our PRP before and after gallery to see the visible improvements achieved by our patients.

How Long Does It Take to Prepare a PRP Injection?

The preparation process usually takes 15 to 30 minutes. The blood draw and centrifugation steps are quick, and the injection is done during the same appointment. This convenience makes it a preferred option for patients seeking non-surgical alternatives.

How Long Do PRP Results Last?

Results are not immediate. Patients generally begin to notice changes after three to six weeks, and full effects often appear within three to six months. On average, improvements can last anywhere from 6 to 12 months, depending on individual response and the condition being treated.

For Hair and Hair Loss

In hair restoration, benefits last about 9 to 12 months. Maintenance sessions are advised every 6 to 12 months to support hair density and growth. Factors like age, health, and the degree of thinning play a role in durability. If you’re curious about real patient outcomes, explore our detailed PRP injections before and after results.

For Face and Under Eyes

When used on the face and under-eye area, this treatment helps improve skin tone, texture, and tightness. These enhancements often remain visible for 6 to 9 months. Routine touch-ups can help extend the youthful appearance.

For Knee Pain

In orthopedic cases such as knee therapy, relief may continue for 6 to 12 months. Some individuals experience longer-lasting comfort when the treatment is combined with exercise or lifestyle adjustments. It is also commonly used as a supplement to other treatment options for chronic joint pain.

Recovery and Expectations

How Long Does It Take for PRP to Work?

Noticeable changes typically begin after a few weeks. The body requires time to respond to the introduced growth factors and initiate cell repair. One of the primary effects is that it reduces inflammation in the treated tissue.

Pain, Recovery, and What to Expect

Does a PRP injection hurt? Most patients report only mild discomfort, similar to a brief pinch. Any soreness usually subsides within a day or two. After a PRP shot, slight redness or swelling is common but temporary.
