We recommend our patients to start 20 days after the surgery with Rogaine 5% (Minoxidil) foam spray twice a day but this can change due to your own surgeons recommendation. Please consult with your surgeon about his/her after care recommendations.
If there is a trust issue, you can ask for the surgical record and a record of the number of grafts should be there. Trust seems to be a problem but the photos don't help me help you.
