Shampooing at 2 weeks after the procedure is alright. Do it gently with fingertips without using nails. The scabs ideally should come off by 10days post hair transplant. After this the scabs start getting firmly attached to the skin which is no good. As far as the graft dislodgement is...
Do not pick at those scabs or you risk disrupting the grafts. It will eventually resolve. You could dab a little hydrogen peroxide to get rid of the dried blood.
Exposing your head to sun after the operation is not healthy for the transplanted hair. Use your supplements and make sure you wear a hat next time.
