One of the most common types of hair loss is androgenic alopecia, also known as male pattern baldness, and is a cause of many complaints in the dermatological clinic. Even with many options of treatment for this condition, Platelet-Rich Therapy (PRP) is a highlight as it uses regenerative medicine to promote hair growth and prevent hair loss.
It basically reintroduces the growth factors and other beneficial cells found on the blood drawn from the patient itself into the scalp through injections performed by a specialist. The blood cells will stimulate hair growth by amplifying the natural growth factors that the body uses to heal tissue naturally, without foreign substances. Beyond hair loss, it can be used in cases of injuries or damage to tendons, ligaments, muscles, joints, and skin.
The preparation of Platelet-Rich Therapy is performed by drawing the patient’s blood and with a special centrifuge system, the growth factors and active proteins are collected and applied in sessions of 30 minutes. The whole treatment is recommended to have three sessions of the procedure.
Although the invasive injections on the scalp, the PRP is considered a low-risk procedure and with very minimal side effects like soreness and bruising at the injection site. Allergies are also very rare, as the treatment is done with the patient’s own plasma and cells, especially when compared to traditional medications.
This way, when properly done, the PRP is a quick and efficient technique to improve bald areas, promoting growth, making the present hair stronger and with less loss.
