Yea, I messed up and shaved my head, I thought all the scabs were off but I started bleeding in one spot. I wanted to see how I looked shaved, do you think I lost a graft 12 days post op? GRRRRRRRRRRRR
they say 6-9 days the grafts are permanent. I have a set of blade clippers that REALLY tug at times though so if yours are like that its still possible that force could rip it loose. If you used a blade your fine, the blade probably just skinned the top of a scab or healing bump.
