These scabs (crusts) should have been prevented with good washing techniques the day and the day after surgery. Once they form, you run a risk of graft loss until 14 days at which time you can get them out by leaving a shampoo on the area for 10 minutes, getting it water logged, and then gently rub them off with your finger tips. Repeat this daily until the area is crust free. I take it that you are a female as the hairline shape, a concave shape, is the classic female pattern.
