Hello MarkoPol, thank you for this question! Drinking alcohol the day after a scalp PRP (Platelet-Rich Plasma) treatment isn't ideal, but it's not necessarily catastrophic. The main concerns with alcohol consumption after PRP treatment include: Increased Bleeding Risk: Alcohol can thin your blood and potentially increase bleeding or bruising at the injection sites. Healing Interference: Alcohol can impair your body's ability to heal and might affect the effectiveness of the PRP treatment. Dehydration: Alcohol can dehydrate you, which might affect your scalp's recovery process. While a small amount of alcohol occasionally might not cause significant issues, it's generally recommended to avoid it for at least 24-48 hours after the procedure to optimize healing. If you have any concerns or notice unusual symptoms, be sure to reach out to your provider. I hope this helps!
