What to avoid after PRP scalp injections

What to Avoid After PRP Scalp Injections: Essential Aftercare Guide PRP (Platelet-Rich Plasma) scalp injections are a popular treatment for hair loss because they are minimally invasive and use your own blood to stimulate hair follicles. While the procedure itself is simple, aftercare plays a major role in how effective the results will be. What you do—or avoid—after PRP can directly affect healing, comfort, and long-term hair regrowth. This guide explains everything you should avoid after PRP scalp injections to ensure the best possible outcome. Why Aftercare After PRP Matters After PRP injections, your scalp enters a healing and activation phase. During this time: Growth factors are being absorbed Hair follicles are becoming stimulated The scalp is slightly sensitive and inflamed If you expose the scalp to irritation, heat, or contamination too early, it may: Slow healing Reduce treatment effectiveness Increase discomfort or side effects Proper aftercare helps PRP work at its full potential. 1. Avoid Washing Your Hair Immediately One of the most important rules after PRP is to avoid washing your hair for at least 24 hours. Why: The PRP needs time to absorb into the scalp Washing too early may reduce effectiveness The scalp is still sensitive after injections After 24–48 hours, you can gently wash your hair using a mild shampoo.
