Hey I had HT around 5 weeks ago. I've got grafts in forehead and some on crown. My surgeon advised me that I can start use minoxidil after 3 weeks so did I but only in crown area. After 4-5 weeks I noticed that I have died skin and a lot of dandruff. I started to scratch crown softly by fingers to take out this died skin but I noticed that flakes came out with the transplanted hair. Is it possibility that I damaged grafts on my recipient area and my HT in crown area will fail ?
