Your scalp may be somewhat sensitive due to the injection with the mesogun. Be careful when touching and rubbing the treated skin area. It is important to avoid scratching, as this can lead to wounds that can become inflamed in extreme cases. Allow the injected substances the opportunity to work optimally. We advise not to wet your head and/or wash your hair for the first 24 hours after treatment. Sweating is also not recommended. Therefore, postpone a sauna visit or an intensive hour of exercise for a few days.
