Plasma injection therapy, commonly known as platelet-rich plasma (PRP) therapy, is a safe and effective method for stimulating hair growth, improving hair density, and enhancing scalp health. While the procedure is minimally invasive and generally well-tolerated, proper aftercare is essential to maximize results and minimize potential side effects. Following recommended aftercare guidelines ensures that hair follicles respond optimally to the treatment and supports overall scalp recovery. One of the first and most important aftercare tips is to avoid touching or massaging the treated areas for the first 24 hours. Since PRP involves multiple injections into the scalp, touching the area can increase the risk of infection and interfere with the absorption of growth factors into the hair follicles. Patients should also avoid scratching or applying excessive pressure, even if mild redness or itching occurs, as this is a normal part of the healing process.
