7 weeks post op hair transplant, still have scabs. My clinic told me to scrub them out. Is this normal, have I lost grafts?

Hello, great question. Yes you can scrub to remove the existing scabs with no damage done to your grafts.

Normal the scab together with transplanted hair will start falling off 2 weeks after surgery. If not, you can start using your fingertip to gently rub it to clean the procedure area. This action might cause the transplanted hair falls out but, no worries, it's normal. Most of them will shed and regrow in the next 3-4 months. 

Thank you for your question! We tell our patients to start with the post-operative hair washing process 3 days after their hair transplant procedures and to follow the instructions once a day for 15 days.  
From the 14th day onwards, you may start massaging your head softly during the washing process. All crusts should be gone within 15 days at the latest. In your case, scabbing has persisted beyond 14 days, which indicates that you haven’t been shampooing vigorously enough. It is safe to shampoo and rub off the crusts with your fingertips until they are all gone.
